I've never had problems with shaky camerawork, not with Blair Witch (which I don'T like that much), not with Cloverfield and I saw both of them on the big screen. My boyfriend got a little nauseous, but he also liked the movie.
Though I don't see any comedy in Cloverfield, it'S serious from start to finish.
If the camerawork turned you off, I guess you could still watch the sequel. I don't think they will repeat the style, Blair Witch 2 was also radically different from the different (and sucked so much that it killed the franchise).
It'S funny, I remember watching Woody Allen's "Husbands and Wives" on the big screen back in the early 90s (yes, I'm that old) and people were getting nauseous from the camerawork because they weren't used to handcamera. Maybe the Cloverfield-style will seem totally normal in twenty years.
I wouldn't call the camera work terribly. Actually, whether you liked Cloverfield, its simple plot and the style in which it's been done or not, the camerawork, editing and directing was outstanding. Just from a technical viewpoint, of course. And I can totally appreciate that.
