Keep in mind that I’m basing that on my kid’s recommendation...but I have to say the gameplay looked fun even in the early stages of the campaign style play. The game play appears to diverge away from the movie plot quite a bit.
Spiderman 3 also diverges away from the movie. It uses a map of Manhattan that has the locations of mission opportunities on it. You click on a mission, get way points so you can swing over to the mission site, and you accomplish a list of objectives. For example, my son started a series of missions last night that are part of a new story involving The Lizard. Plus, the opening intro for the game talks about a brewing gang war.
The coolest part? Bruce Campbell narrates. Bruce is awesome.
