Guilty Pleasure?
Its hard to say this considering how campy, cheesy, and almost laughably bad this movie is...
but I loved it, its such a fun movie to watch, and its not pretentious or self-important; it knows its bad, its comfortable with it.
Not to mention the cast is about as perfect as you can get. Plus, Shelley Duvall is *amazing* (even if she does think aliens live inside her).
