1 Once Upon a Time
There should have been a better thought out plot line for the show as a whole, it felt like the show was making it up season by season.
Also there was a lot of storylines that went nowhere.
2 Danny Phantom
Danny Phantom is an American animated series created by Butch Hartman for Nickelodeon. It was produced by Billionfold Studios and distributed in Canada by Nelvana, a Canadian animation company. The series follows a teenage boy who, after an accident with an unpredictable portal between the human world and the "Ghost Zone", becomes a human-ghost hybrid and takes on the task of saving his town (and the world) from subsequent ghost attacks using an evolving variety of supernatural powers. He is aided in his quest by his two best friends, and later, his older sister, who for most of the series' run are among the only people who know of his double life.
It was hinted in the show that Vlad Masters / Vlad Plasmius would get a redemption story but it never came to fruition, that was a shame.
Also a return of Dark Danny from "The Ultimate Enemy" would have been awesome.
Glee is an American musical comedy-drama television series that aired on the Fox network in the United States from May 19, 2009, to March 20, 2015. It focuses on the fictitious William McKinley High School glee club, New Directions, which competes on the show choir competition circuit while its disparate members deal with social issues, especially regarding sexuality and race, relationships, and learning to become an effective team.
All I can say is this show had some of the worst plot holes I have ever seen like Rachel dropping out from a Broadway show to star in a TV show. The whole series was about her dream being a big Broadway star. On top of the the most of the characters had very little character development and seemed to get worse as the show went on. Overall this show was a disaster after the first season.
Gargoyles is an American animated series produced by Walt Disney Television Animation and Buena Vista Television, and originally aired from October 24, 1994 to February 15, 1997. The series features a species of nocturnal creatures known as gargoyles that turn to stone during the day.
I felt the show went downhill when the human public found out about the Gargoyles, way to much drama after that, with Season 3 being dreadful. Would have been better if the Gargoyles remained the secret defenders of New York.
5 Adventures of the Gummi Bears
I would love to see a remake of Gummi Bears, like the way Disney did a remake of the Ducktales series. The biggest change I would make is that the villain Duke Sigmund Igthorn would have a daughter he truly loved and he that he blames King Gregor for the death of his wife. I imagine Igthorn's daughter being very sarcastic and cynical but has a soft spot for her father and the ogres. In fact I see the ogres saving her life after her dad was banished at which time Igthorn seized control of Castle Drekmore and the ogres. Also I see Igthorn daughter and Princess Calla being great friends before the banishment but now there's a great rivalry between them.
I really don't see a remake coming due to a trade mark issue with the phrase "Gummi Bear".
Supergirl is the superhero name of Kara Zor-El, cousin to Superman. She was created by writer Otto Binder and designed by artist Al Plastino in 1959, and she first appeared in Action Comics, in whose first issue Superman himself was introduced.
Kara Zor-El's Supergirl has been adapted into various media, including television and film, having being played by Helen Slater, Laura Vandervoort, and most recently Melissa Benoist in the Arrowverse.
The biggest mistake the show made was how the writing was so painfully predictable between Supergirl and Lena Luthor. We knew if Supergirl didn't tell Lena about her secret identity, Kara Danvers, Lena would get very angry and fell deeply hurt that Kara didn't trust with her secret especially since basically everyone else knew. And surprise, surprise, that's exactly what happened. The writers could of chosen a less predictable path to go down but they just decided to copy the Smallville storyline. To sum it up, the shows biggest mistake was lazy writing.
7 The Legend of Korra
The Legend of Korra is an American animated television series that aired on the Nickelodeon television network from 2012 to 2014. It was created by Bryan Konietzko and Michael Dante DiMartino as a sequel to Avatar: The Last Airbender.
8 Tangled: The Series
Great first two season but the show made a mistake when they had Cassandra betray Rapunzel, would have been better if somehow Gothel came back to life on the season 2 finale and she took the role Cassandra had in season 3.
Everything we want to be 2D is CGI.

9 OK K.O.! Let's Be Heroes
OK K.O.! Let's Be Heroes is an American superhero comedy animated series created by Ian Jones-Quartey.
10 Game of Thrones
Game of Thrones is an American fantasy drama television series created by David Benioff and D. B. Weiss. It is an adaptation of A Song of Ice and Fire, George R. R. Martin's series of fantasy novels, the first of which is titled A Game of Thrones.
The show was amazing until the last season. First they destroyed Daenerys character by making her insane like her dad and killed a lot of innocent people. Then you have John Snow character making a lot of dumb decisions which contributed to Daenerys going insane. Lastly making Bran king was so random it just made the fans angry. Overall this show was amazing until the last season. If you are going to watch it just skip the last season and you will be happy.
I wasn't really interested in watching this show, but tried it out anyways. Didn't care much for it tbh.
11 The 100

12 Earthworm Jim: The Animated Series
13 Jackie Chan Adventures
Jackie Chan Adventures is an American animated television series starring the adventures of a fictionalized version of action film star Jackie Chan.
In the later seasons it would have been exciting to see Jade transform back into the Queen of the Shadowkhan. So much hinting at that in season 4 but it never happened.
To be honest I don't see a grownup Jade becoming a white knight hero like her Uncle Jackie, I believe she would have gotten bored with that life, I see Jade either becoming an antihero or a leader of a crime syndicate of thieves with a code.
14 The Ren & Stimpy Show
The Ren & Stimpy Show, often simply referred to as Ren & Stimpy, is an American animated television series created by John Kricfalusi for Nickelodeon.
This haunting series follows the thrilling yet terrifying journeys of Sam and Dean Winchester, two brothers who face an increasingly sinister landscape as they hunt monsters. After losing their mother to a supernatural force, the brothers were raised by their father as soldiers who track mysterious and demonic creatures. Violent memories and relationship-threatening secrets add additional burdens on Sam and Dean as they investigate all things that go bump in the night. As old tricks and tools are rendered useless and friends betray them, the brothers must rely on each other as they encounter new enemies
To be honest, the show's "high stakes" started to die down after season 11.
16 Star vs. the Forces of Evil

22 Foster's Home for Imaginary Friends
Foster's Home for Imaginary Friends is an American animated television series created by Craig McCracken for Cartoon Network Studios.
23 Star Trek: Enterprise
The show started off OK but it ended quite bad. The main problem with Star Trek: Enterprise is that the show had to live up to the legacy of the Original Series, The Next Generation, Deep Space 9 and Voyager which was very difficult. The show's theme song, despite being a good song in it's own right, was also incredibly out of place as a Star Trek theme.
The show is still miles better than Discovery & Picard.
24 Xiaolin Showdown
Xiaolin Showdown is an American animated television series that aired on Kids WB and was created by Christy Hui.
25 Peppa Pig
