Meh, it was pretty bad. too rediculous and obvious, every number can be broken into series of 2s and 3s, it's a commonly known mathematical fact (as they are to two lowest prime numbers). To become obsessed with the fact doesn't really make sense. then again that wasn't necessarily the point. The twist was actually decent but really, it didn't save the fact that the movie was overwhelmingly average.
It was only really good for killing some time.
Worst line ever:
"32...that's 23 in Reverse!!!!!1111one!"
