I can think of 2 recent movies, Oceans Eleven and Thomas Crowne Affair, that were as good as or better than the original. For the most part, I think they should leave the originals alone. Otherwise, they just crap on them. Can you imagine Casablanca redone for today? Jim Carrey spazzing out and pop culture references? Sounds delictable.
Oh, and I liked the remake of the Italian Job, too. However, I wouldnt really call any of the 3 flicks I mentioned here as classics. They can stick to redoing neverheardofs from the 60s, but leave the good ones alone.
