I'll be honest... I find the movie design (with all the lines and textures) a little busy, especially when it's powered up. Then again, I have the same problem with a lot of comic-book designs of late.
What people are talking about, really, is a lack of
shading. Solid black only works when the character is designed to look that way (e.g. Cloak or the original Havok design). Otherwise, it just looks lazy, IMO.
Give me some believable shading, and a few accents to spice it up, and I'm happy. Something like this, maybe, but with modern coloring:
(I confess, I miss the gold. It just pops better on the page)
