I saw both 'I am Legend' and 'Meet the Spartans' at the movies. I am Legend freaked me out so much, but maybe that's just because I'm a wimp (and was in I-Max!!), and Meet the Spartans-while better than Epic Movie, was still pretty crap.
At the movies: Enchanted. Didn't do much for me, but James Marsden definitely made it worth it.
On DVD: Jaws. No matter how many times I see it, as soon as that tune starts playing I sink into my blanket.
