I'm biased on this as I am a True Believer and Marvel Comics has been a part of my lifetime for ever. I also am a 3D Artist and Digital Special Effects Artists, and the SFX in this Film are over the TOP! Wait till the next one comes out the SFX will be 100X more amazing. One Copy for me and One for the Family.
What's great about it: Special Effects and Excellent Acting
What's not so great: Needed more Super heros.....:-)
Excellent movie great FX and edge of your seat plot! All of the actors are fitting of the parts they play especially Robert Downey Jr. who is a mirror image of the comic book version of Tony Stark.
