IMO, the Web Rush feature is very cool. Now, when you start talking about how many times he did a barrel roll and what not, you gotta take into consideration, its not known how often you may see that animation when you actually play the game. Manhattan is full of buildings and structures of different sizes, no telling how he may go about getting to them when using Web Rush. I seriously don't think Beenox went out of their way to create 100+ different animations for one gameplay element that is virtually a glorified cinematic, partially interactive trip skip button. This feature is something that has never been done before in a Spider-Man game, so who knows, they may wanted to keep the animation count low for this feature to see how it fares with the audience. Given if everyone likes the feature, the next game may feature more animations and stuff.
