Unrealistic (Spoilers)
Alan Johnson claims he knew Charlie Fineman from their college years and that they were roommates. I can't be the only one who found this to be unrealistic and assumed it was a lie made by Alan because how would minorities be roommates with other people. When Charlie didn't recognize him at all, I immediately thought Alan was making it up just to take advantage of Charlie.
Don Cheadle was most definitely miscast. His role should have went to someone who would looks more similar to Adam Sandler so it would be believable for them to have been roommates. Otherwise good film!
