Huh. Not sure what to think, really - and I'm a longtime anime fan.
Admittedly, the Iron Man clip looks pretty wicked - though it looks like they got Captain Harlock to play the heavy. It's weird - they've got the really slick looking movie-based Iron Man armor, but the villain and the girl (Pepper, I presume?) look rather retro by comparison. It's creating a weird kind of imbalance for me, aesthetically speaking.
Wolverine is a bit disappointing for me. They could've taken his chara design in so many more interesting and more character-appropriate directions and instead chose to go with a bland pretty-boy incarnation, instead. Maybe something scruffier, more along the lines of Jubei from Ninja Scroll would've been more appropriate. Sorry to be so narrow minded, but it ain't Wolvie without the muttonchops.
