Great Idea, Poor Ending

Rating: 7/10 (16 October 2009)

This is a great idea. A technical genius who is somehow able to commit revenge murders from his jail cell. He doesn't hide the fact he's a killer; in fact he announces each murder just before it happens.
Technically everything was possible and the method very cleverly hidden so I was kept in suspense until the last 20 minutes when the cat was let out of the bag too early. The ending is a let down. It's true Hollywood: Technically improbable, illogical, and in my opinion it spoils all the character development made until that point and wastes the opportunity for a much darker ending with a more satisfying outcome.
All that said I really enjoyed it. I would recommend it to anyone not disturbed by moderate violence. Go see it!
