Spider-Man was an interesting reboot, very typical of Marvel's usual 'no, wait, let's retcon THIS!' M.O. Would have liked to have seen it tied into the Avengers franchise (in the comics he eventually joins up with them), but licensing disputes prevented that from happening.
Rock of Ages was pretty awesome, although I admit I'm somewhat biased; I'm among the ever-smaller percentage of the population that still really likes
Tom Cruise, and the soundtrack of my life pretty much came straight from the eighties, so there's not a lot of ways the movie could have missed for me.
That said, it's a very well-done movie. The cast does all their own singing, and Tom absolutely owns
the character of Stacee Jaxx. If acting ever fails him, he has the charisma to make it as an arena rock star. IMHO, his performance of 'Pour Some Sugar On Me' is not to be missed. So here, don't miss it! http://www.youtube.com/watch?v=D35KdQKNeW0&feature=related
I'll add that it's the first role I've ever seen Alec Baldwin in where I actually *liked* him, usually I think he's just a smarmy bastard, but his Dennis Dupree wound up becoming my favorite character in the movie.
