He's gotten better in some of the newest episodes lately.
At first he was a dumb but sort of lovable character, but now he's just a jerk and it seems like he knowingly pretends to be dumb to annoy others.
I really miss old patrick. Now he is a huge Jerk
Not anymore but still not as good as Pre-movie spongebob. Through at least he is not using his acting skills to annoy others - toptenforlife

7 Cosmo - Fairly Odd Parents
Cosmo is Timmy fairy godfather. He's Wanda's husband and Poof's dad.
Cosmo is very immature and stupid, but also very charming and a loving father, godfather and husband.
It'd be better if they didn't have to make Daran Norris crank up Cosmo's voice and stupidity to nigh-intolerable levels of annoyance. Seriously, there's none of that lovable charm Cosmo once had come later seasons. - ModernSpongeBobSucks

Timothy "Timmy" Tiberius Turner is a ten-year old boy who is a fictional character and the main protagonist of the American animated series The Fairly OddParents created by Butch Hartman for Nickelodeon.
Chloe's arguably still worse than him no matter what season, but that doesn't mean he's completely safe from Flanderization. He used to be a very sympathetic character in the early seasons. While he was impulsive at times, he was usually a kid with a good heart who truly loved his fairies. However, I can't be the only one who notices he's gotten more selfish and reckless over the later seasons. In other words, he went from being sympathetic and kindhearted protagonist to an absolute douchebag. - ModernSpongeBobSucks
