Star Trek Trailer - Short and sweet. Some people actually booed. Not a good sign for Abrams. He's going to have an uphill battle bringing respectability back to the franchise. Not worth the price of admission. However...
Cloverfield (No Spoilers) - The best two words I can think of to describe this movie are "fucking fun." It's been a long time since I've had this good of a time at the movies. I've tried to stay away from too much information as far as the flick is concerned by I did read a review that described it as a "roller coaster ride." I think that's a perfect way to describe the movie. Periods of tension interupted by terror.
It's also the perfect antidote to the bloody schlockfests that pretty much define horror these days. Not much blood but plenty of scares.
(Oh, and the monster wasn't the Stay-Puft man.)
J.J. Abrams - well done, sir.
