This movie set a new bar for horror/survival/sci-fi flicks. I enjoyed it tremendously. Going to see it tomorrow for a third time. CGI was fantastic. Acting (even though they were newbies) was well done. None of that Blair Witch Project nonsense. The ending left a lot of questions much like Alfred Hitchcock, the king of suspense did in his films. It paid homage to him in this way. Epic, engaging, creepy and exciting. The camera work made it feel more real. I could hear everyone talking and yelling "Run!" or "What are they doing?!" I think I even heard a few "Holy!" exclamations. Well done movie. Brought the monster movie genre back to screaming and stomping life.
EDIT: I disagree with those who say it went down hill after Brooklyn Bridge. It was just as amazing. Cool stuff. Very well done. My favorite scene involved (SPOILER)when the head of Lady Liberty went flying through the air. It was haunting. To see that beacon of freedom just ruined. Reminds me of the train scene in War of the Worlds (remake) when the burning train goes flying by. Just very haunting and takes the breath away. Another scene that made a wonderful add to the creepy factor was Marlena's death. It was just a glimpse through a plastic cover of her seeming to split apart and then wham she's gone. I loved this movie because it doesn't have the typical horror techniques of today. It let's tension and suspense build and that tends to make people scared. I'd always been slightly disappointed by this genre of movie in the past. All of that changed with Cloverfield. Now I'm as pleased as little girl with her favorite flavor of icecream.
