I hated how he became the symbol now of people who're desperately quirky. You couldn't throw a damn rock without it hitting some average person who closely associates with Deadpool because "he's like me! I say and do random shit for the lulz and so does he and that's all foonay!".
And yes he is fucking obnoxious to the nth degree, he isn't creatively written or crafty with his wits. People just think "oh Deadpool is totally the guy who'd ride a unicorn into battle....BECAUSE IT'S DEADPOOL! HAW HAW HAW!!". Like I don't think I want Deadpool to be overly serious or edgy, I just want him to be written not in the way he is now. I just feel there could be more there because he's not a character anymore - he's noise. Loud and obnoxious noise.
