> The problem with Spiderman was that the CGI was unconvincing, not that it was "clearly CGI." Most, though not all, of the shots of Spiderman in action looked weightless. He didn't move in a convincing manner. I can accept that a superhero can leap tall buildings with a single bound and cling to walls, but I can't accept that forces are not countered by equal and opposite reactions, or that acceleration due to gravity varies according to the whims of animators.

Intuitor.com has done a brief review of the physics in Spiderman. They have a couple other movie physics review on that site, too... the only films to get perfect reviews so far are "Seven Years in Tibet" and "Road to Perdition". Go figure. (Granted, there aren't too many movies on there, but the point sort of holds.)
