I dont understand the hate for Wadlow's script and direction.
His script is magnificent: Every main character has a unique storyline which gives them their own motivation over the time. Much better than in the first movie where only Dave has a real character development. The relationship between Dave and Mindy has a great build up and makes so much more sense than Webb's Peter and Gwen nonsense. Chris D'Amigo is one of the best villian with an all-time character arc since years. So much fun to watch his journey to get revenge than Loki, Bane, Lizard or whatever other one dimensional character was thrown at me in other comicbook movies.
The supporting cast is great especially Javier, Colonel Stars and Strips, Marty and Marcus. Most of the one liners are great.
The best part of the script are the small things, something you will easily miss if you watch this movie only once.
My problem with the script is Todd. But at least he is doing something in this movie.
I see that Wadlow has not Vaughn's style. It quite obvious. But i do not have a problem with it. Kick-Ass is not only "style over substance". Even the first movie offers more than violence.
And the action scenes are way better than anything Nolan put into his Batman movies.
In the end this movie is so much better than The Amazing Spider or The Dark Knight Rises. And yet KA2 gets trashed by critics and critized by fans.
