I watched this last night with my wife, and within about 45 minutes it turned into an episode of MST3K. The film was jagged, poorly edited, and had terrible camera work. There are several little minor clip scenes inserted into the film that never get explained, for example. The Lars character comes into the movie with NO explanation, you never even know who he is until 5 minutes after he's in scene. The dialogue is terrible. The conversations are unbelievable, not for their audacity but for the fact that they make no sense! Most of the acting here is terrible. The overall writing is horrid. The Puffball itself never gets tied into the movie - this film seems to assume you've read the book or have a clue what's going on, because it doesn't explain almost any of it.
