I absolutely loved this film - best I've seen in a while. Yes, it was cheesy with the whole "Must save the woman I love" storyline, I mean, they could have dispensed with that by just having them be unable to leave the city or something (no bridges, no helicopters... I don't know, something!) but other than that it was really really good. Not scary, unfortunately, but a really good watch nonetheless. I especially liked how the sound was so loud in the cinema that when there was an explosion or a tremor in NY in the film, you actually felt the floor and seat shaking! It really added to the effect and made me feel like I was there with them.
The one nit I must pick with this film is the night-vision scene in the tunnels. We could see what was going on due to the night-vision, but how did everyone else (i.e. Rob, Lily and Marlene) know what was going on? Because up until then they hadn't been able to see very far with the camera torch. It was only when night-vision was turned on that we (and Hud) got to see what was happening... that's the only problem I had with it though!
Some people on here are saying that Rob and Beth were a "past couple". I didn't get that impression. From what I could tell during the party scene, Rob and Beth had been best frienRAB for years and slept with each other one time like a month before the attack. Isn't that right?
Also, could someone please explain to me what exactly happened to Marlene after the blue radiation suited guys took her away (post Maya from Heroes-style eye-bleeding)? I didn't really see what happened due to the shaky camera (which I'm not complaining about by the way because I thought it was brilliant and completely added to the effect)?
