Yeah, I just got back from the theaters and saw Cloverfield as well. My views are probably the same as Glorb's about it. It wasn't great, but was pretty cool. Pretty freaky at points, and the action-y parts made me a little hyper, but nothing too bad. I just really didn't like the plot is all. 3.5/5 stars at best, for a cool movie.
That drawing actually is spot-on I'd say. Of course it lacks detail, but it has the main features, so very good, Glorb!
