After the Dark

As other people have detailed more completely than I care to, this movie is mediocre at best if you're looking for a movie about philosophy. If you try to watch the movie from this point of view it's downright infuriating and deserves the single star that so many reviewers gave.

Watching the movie as a drama, it's passable. The teacher claims that they're doing a thought experiment but in actuality I would say they were playing a bad role playing game (think Dungeons and Dragons). Imagine a really nasty DM (the teacher) empowered to force others to play his game by use of his position of authority. He does most of the things that a bad DM does and for reasons consistent with most common role playing game drama. This doesn't really pull together to make a fantastic movie but it's decent.
