FUCKING AWESOME!!! And to be honest I'm surprised it's only got a 7.9 on imdb.
It's a monster movie, set in Manhatten, everything's shown from the persepctive of the "Average Joe" who's caught up in the middle of it all.
Utilising the 'camcorder generation' stylings, where the whole film is supposed to be POV from whichever character's filming at the time, it works brilliantly, draws you right into the action (distrurbingly so at one point) and keeps you there.
I'm not gonna go into details but needless to say by the time the credits rolled, and the lights went up, it seemed like everyone in the cinema had been left numb from the assault.
Sure there's a couple of cliches in there, but Cloverfield is an original, interesting and fucking intense take on the monster movie. This and The Host reign supreme at the mo.
Cloverfield - 10/10
