Hypnotic

Yes you could claim, that something like this can be written by someone in their sleep. Puns aside, the execution is quite well done though. The acting is decent. And while it is more than likely that you have seen something like this before - or even if not, you'll be able to guess where this is going ... it still can be entertaining or suspensful enough to watch.

That being said, suspension of disbelief is needed to say the least. Not the best movie ever made of course, but also not the worst by a long shot. Decent is a word I'd use. No need to recap the story.
