I stopped watching this after 10 minutes
I'm actaully ashamed to admit I actaully watched the first 10 minutes.
If I wasn't so lazy to program negative ratings (stars) into this CMS, this movie would would get -100/5 stars.

in a nutshell

the fact this movie somehow made it to theaters make me lose faith humanity

Birthdays are good for you. Statistics show that the people who have the most live the longest.
