It's going to be hard to make a sequel to Cloverfield. Strike that. It's going to be hard to make an imaginative sequel to Cloverfield.

There's two obvious courses that present themselves, both variations on the same idea.

The first is to repeat the handheld angle verbatim and show the monster attacking another major metropolis, but short of using the Eiffel Tower as a toothpick, it's going to be pretty hard to find a city as iconic as New York to trash. The second idea is to repeat the handheld angle, but from a different perspective in the same monster attack, giving more information (contextual or otherwise) on what happened in the first film.

But J.J. Abrams is hinting he'll do neither. In an interview he gave to Reelzchannel, Abrams said that the handheld camera angle would likely get pretty tedious if done too much. Even better, he seems to be at least considering the concept of introducing another monster, or scrapping the first film's monster altogether. Given how utterly impoverished of imagination that monster design was, that would be a good thing, in my book.
