Cloverfield, from what I have heard, is just a monster destroying New York City. Pretty simple concept, sort of like Godzilla, I guess.
I've heard, but have no idea if it's true, that it is based on H.P. Lovecraft's monster - and if that is the case, and the movie is well done, it could be the coolest thing ever.
As for movies, my girlfriend and I have been trying to get caught up this week.
In the last few days I've seen Alien Vs. Predator, Sweeney Todd (sp?), No Country For Old Men, Hot Fuzz, and tomorrow we're going to see Juno in the early afternoon and National Treasure 2 a little later.
No Country might have been the best movie I've seen in the last year or two - it was absolutely brilliant.
