Cloverfield is the codename for a Manhattan event, documented using handheld camera by 5 young New Yorkers throwing a going-away party the night a monster attacks the city.
Essentially that sums up the entire movie. That’s both good and bad, mostly good. The handheld feel and the fact that we don’t see the monster in anything but short flashes, works really well, almost as well as it did with Alien. Despite the premise of the film, the plot is actually somewhat believable, which is impressive considering it’s a monster-flick.
Cloverfield works on many levels, and it’s definately worth 5 stars. To have earned the sixth star, however, I would personally have wanted a more fleshed-out and detailed ending, possibly one that wasn’t so predictable.
