The CGI doesn't look too good.

And this is behind, so those are most likely finished shots.
Marvel is paying for this movie, Universal is only distributing. They borrowed 120,000,000 from Merill Lynch.
Word was that they didn't want to bring back the greatest and most expensive effects house (Industrial Light and Magic/George Lucas) to handle this...and it shows. Abomination looks nothing like the Comic Abomination. The Hulk doesn't look as good either.
They couldn't afford WETA either (Gollum, Kong). You get what you pay for.
By the way, Lucas is doing the fx for Iron Man...which looks stupendous. And of course, he is doing the effects for IJ and the Kingdom of the Crystal Skull since well, he created it and owns it.
