Uncle Billy
For the most part I loved this film, but my biggest gripe with it was the catalyst for George's breakdown. Uncle Billy is really THAT stupid to GIVE $8000 to Mr Potter, their archnemesis, and has absolutely no idea about it? Up until that point I thought the plot was remarkably believable and realistic, which I was pleasantly surprised by.
I guess that if they had tried to pin the missing money as an evil scheme by Mr Potter right from the start, it would've been a corny plot line and a lil one dimensional. BUT to have Uncle Billy just give the money to Potter? Come on, that's just weak.
