From the clips I saw on youtube, it seemed like some dramatic unsolved mystery show. There was very little talk about the chess played. If you are looking for a documentary on the controversy, it might be just what you are looking for. If you are looking to understand what happened on the board, you would be better off just studying the games. Of course, I have not seen the whole thing, so maybe someone else could answer your question better. Hope that helps.

I am thinking about buying the movie Game Over Kasparov and the Machine. Is it any good? Help.
