This movie was none of the things I thought it would be. Completely beyond me how this is receiving high ratings.

It's all over the place related to the rules it establishes for it's universe. Without spoiling anything there is no way you could randomly evoke an instance of yourself with specific sets of skills. It would take a million tries but with this... no.

If you put even the slightest thought into this it falls apart.

The other thing is they often go quite low brow with the humor and its usually not very funny. I did laugh a few times at random but most of the bits missed me.
