i think this critic's blurb pretty much sums it up:
"It feels entirely made by committee the definition of house style, without a personal stamp in sight."
that's The Telegraph, here's Time Out New York: "This is a superhero movie that feels like it might have been made by anyone and no one at the same time, simply space-filler before the next big team-up movie."
listen, almost all of these Marvel movies are effective as well-made and broadly appealing entertainment and fan service, but for them to reach their full potential as works of cinematic art and not just comic book ports, MS and Feige need to encourage the visions and artistic identities of the individual directors involved and stop pushing Whedon's way of doing things just because dude made the most successful Marvel movie to date. guy is an accomplished geek-indulger but i doubt he'll ever sniff most Top 100 Directors lists.
love or hate Nolan's Bat flicks, they had something in spades that Marvel movies, by and large, don't. and that's the singular voice of their director.
