Top Ten Problems with Harem Anime
Not all items apply to every harem anime. Most of these items are about female harems, not reverse harems. Some of these items can apply to other anime genres, or anime in general.Thanks to Longesthorn for the idea.
Dense in the form of tripping on thin air hard enough to fly across the room and land on a girl, usually the tsundere because she somehow happens to be right there. His hand conveniently lands on her breasts, somehow under her shirt and bra, and instead of immediately getting up when he realizes it, he squeezes her chest while mouthing some lame apology then gets blasted into space.
When the lead is unlovable like this, the harem ends up feeling 100% forced. It seems there's no proper reason for the girls to choose to crowd around him instead of a cute, interesting, smart, and caring guy. Dumb characters are not funny when they screw up in every single episode.
Many of the girls feel like they've just been put there for the sake of the harem or shallow 'fanservice' scenes. They're still people with just as many (if not more) thoughts and feelings as the highly developed lead.
Also, if there was more focus on their relationships with characters other than the main one, there would be much more of a natural sense of community. A social circle that would completely fall apart without the lead is a huge sign of poor writing.
It's one thing to have sexy scenes. It's another if your female characters are little more than blow-up dolls.
The indecisiveness of the lead that could eventually lose him all the girls can get very annoying. Viewers just get left with the feeling that they watched 50 episodes all for nothing.
Especially if the anime is going to be long, the events of it must be engaging and deep in progression and resolution for it to be worth watching and to encourage viewers to empathize more with the characters.
This is a sign of laziness. When this happens, the anime will mainly consist of filler and minor developments and leave the more major developments to the end. It's a poor attempt at trying to pace the "plot" out.
AKA the time most of the audience are already too bored to carry on watching.
The Newcomers
The main character is often only nice to pretty girls. Being nice to someone you find attractive is common sense, not a sign of the goodness of your heart. Acting nice and polite is not uncommon or a big deal. The Nice Guy (TM) is not doing anything special.
There is nothing about the main character that stands out. Guys like that are a dime a dozen. It is incomprehensible and unbelievable that their love interests have never met someone like the main character before.
There is always one predetermined girl the lead is supposed to be with instead of the one who he "should" be with.
It always kills me how there is an obvious girl in the group that's blatantly pervy either towards the male lead or any of the other female characters, and all she gets is weird looks while the male character gets hit for possibly thinking about something perverted when he sees it, never mind him being just as put off by the scene.
