Edited nicer version :-)
I LOVED this movie. I've been waiting to see this since I spent the first 15 minutes of Transformers wondering what that 1-18-08 trailer was all about.
I will say that when I buy this DVD (which will be the day it comes out) I can fast forward through the first 15-20 minutes of the movie. Once you learn who the main characters are, you just want to get to the action. But once the action starts, it continues right through to the end.
The reasons that many people are giving for hating this movie are mostly the reasons that I admire it. I don't care where the creature came from, I like not knowing if they killed it, and I like not having a full explanation for the events documented here. The camera work is not as erratic as I thought it would be. I got more queasy during the asteroid landing scenes in Armageddon than here.
And the creature itself is pretty cool. It's like nothing I've seen before and you can't really accurately describe it to your friends. I expected to not see much of it, but you get many good views from different angles (including a surprising one near the end).
All in all, when the movie was over there was dead silence in the theater. Honestly, I'm sure some of that was disappointment or people just not understanding what happened. For me, I didn't want to move just in case the theater staff would let me stay for the next showing. I would call it a great popcorn movie but when it ended, I looked over and realized I still had 3/4 of a bag left because I never wanted to take my eyes off of the screen even for a second.
I will be seeing this again this week in the theater and would absolutely rate it as one of the best movies I have seen in a while. It's by no means perfection, but a damn fun movie to go see.
