There's nothing wrong with that. it's not *particularly* awesome (and the Doc Ock redesign reminds me of the mulians from RahXephon) but it's hardly worth the kind of vitriol people are putting out.
There's some minor complaints, but seriously, when people are complaining on irrelevant details of something they don't like, beacuse they don't like other parts of it, it's just getting annoying.
