This is not the total disaster that common consensus confirms. It continues the outrageous comedy of the original and still cares about the characters. The satire is unfortunately misguided in places and there are structural issues with the plot (Jim Carrey's heavily marketed performance is pretty much redundant). I would still watch a third one...
Would have loved this movie if I was 10 years old. The execution just wasn't as strong as it was on the first one. Didn't get a lot out of it. Chloe Grace Moretz's character's personal dilemma is just another milked out growing up/maturity theme. Felt uninspired. Still a fan of the fight sequences.
Superhero flicks largely rest on the performance of their villain(s) and Christopher Mintz-Plasse is no Mark Strong. You can see everything coming from a mile away and the original's fun was largely replaced with darkness-for-the-sake-of-darkness. At least Chloë Grace Moretz was still awesome.
I didn't mind Kick-Ass 2, but knowing damn well that half of the stuff in the book wouldn't make it to the movie my expectations were low. Jim Carrey was good for as brief as his role was. The violence was fun but the thing between Kick-Ass & Hit Girl towards the end was weird. Uneven and slightly bi-polar but kind of fun.
Though it lacks the fun tone provided by the first installment this sequel still offers its pleasure especially in the great performance by Chloe Grace Moretz. One often finds one wishing the film was just called 'Hit Girl' already. Regardless, its a fun watch full of ultraviolence with just enough whimsy to still be somewhat of a send-up of the genre. Mintz-Plasse is one note but fun here and Taylor-Johnson bland.
