Spiderman 2 was entertaining and competent. Really liked the dizzying, swooping, darting camerawork. No real complaints, although the train rescue was stretching things a little bit -- even for our friendly neighbourhood superhero. Look out too for the camp horror influences; probably Sam Raimi having fun with his earlier films like the Evil Dead trilogy and Army of Darkness. Chainsaws, lots of screaming. :)
Sony Pictures is really pouring money into the franchise. There will be a third movie, of course, and I hope it doesn't drown under a deluge of easy money and fancy CGI. We'll have to wait till 2007 to find out.
