...again. Anyone who disagrees with you is talking **** right?
No, i didn't say Vaughn for the gig simply because he has done a comic book movie this year.
I picked Vaughn because I know, and i mean KNOW he could nail Avengers.
He has directed ensembles that included megastars, something which Whedon only dreams of. He can shoot sweet action scenes. He has a rapier wit in his writing that doesn't come off as too try hard to be cool like Whedon. He has a realness about him.
Vaughn would be perfect for this gig.
So. i haven't seen Kick Ass yet, but even if it is great, does it mean he should direct every superhero movie? The Dark Knight was great, but should NOlan direct The AVengers? Once upon a time fanboys loved Sam Raimi because Spider-Man 2 was great, post-Spider-Man 3 they act like he raped the entire community.
Directors should be given chances that are solely unique. Vaughn did Layer Cake, a stylish British gangster movie when he signed onto every comic book movie ever and then dropped out (X3, Thor, interest in SM4 and now finally Kickass), but he only did something similar (Stardust) after doing a gangster movie.
The best superhero movies were made by directors who were not in the genre at one point. Nolan? He made mind twisting psychological thrillers like Memento and Insomnia. Favreau? Two children movies (Elf being exceptional, but Tony Stark it wasn't). Raimi? A bunch of low budget horror/comedies and a few low budget dramas prior to taking Spider-Man. Singer? A crime drama and a Nazi movie.
Yet the fanboys either want the directors who succeeded in the genre prior or did pure action movies. But those popular directors did not start in superhero movies or the ones who came from action films (RAtner and Rush Hour and Letterer with the Transporter movies) created mediocre films. Even Avengers is just on "Serenity" level, it will surely be superior to most superhero movies made to date. You can't just go back to directors who already had success in the genre, because they likely will not want to switch ships--and when they do it doesn't always transfer well (Singer moving from X-Men to Superman).
Whedon has a similar style to Abrams and Favreau. Their reboots or superhero movies are generally beloved. I'm sure the similarities in style and how they work with actors crossed Marvel's mind. They want another Iron Man or Star Trek. They don't want another Incredible Hulk/Clash of the Titans. That's why they moved away from your choices.
