I actually just thought of another movie that was probably worth it. I think Ocean's 11 was a worthy re-make, and in a sense a needed re-make in order for Ocean's 12 to exist, and I really liked that movie better then the first, though I would probably be in the minority in that.
There are probably plenty of good re-makes that are, in the end, pointless. I enjoyed Dawn of the Dead, but there was really no need for it. I feel the same for King Kong. I don't know. Re-makes have been apart of Hollywood way before the current re-make explosion. It just seems every other mainstream movie is a re-make these days, and that does suck!
