Cloverfield

Combining low-budget grit with spectacular effects, the film uses its tightly focused, handheld documentary premise (recalling The Blair Witch Project) to make the monster plot extra scary. The lack of context or explanation for the attack echoes feelings of panic on 9/11, when no one could anticipate what would happen next. While the romantic quest to rescue Beth provides a recognizable plot and some events will look familiar (looting, collapsing high-rises and bridges, people using cell phones to document disaster), unlike in many similar films, here you can never be sure what's around the next corner.

But for all its mystery, the monster is mostly an excuse for the film's more ambitious experiment: creating characters out of moment-by-moment action, rather than compelling emotion. As they're thrown almost immediately into chaos, none of them are particularly well-drawn or even sympathetic. Instead, they're emotional sketches of fear and uncertainty rather than individuals with backgrounds and futures. As you can see by the several other anonymous figures who pull out their cell phones to capture the turmoil, the movie's characters are of a generation completely at ease with the concept that they should document everything around them, as well as their own "testimonies." Defined by its time and place (post-9/11 America), the film is clever, harrowing, and a wild ride.
