I'll enjoy any movie that destroys New York, Cloverfield included. Saw it with my partner this past weekend: a few good laughs, a few scary moments, a somewhat interesting POV from the handicam - generally worth the price of the matinee for sure.The fact that the movie was able to keep people's attention so well makes it a hit in my book. Maybe it didn't achieve much in the way of artistic expression or plot or meaning, but it really entertained people, and isn't that the point of a film?
I don't know about anyone else, but I thought the monster was really good looking - sort of like a puppy crossed with a giant lizard. It had a really cute face and eyes, too. Best looking monster I've seen since Alien.
