I will start the ball rolling:
Alien nation (1988) great movie movie about a human cop and an alien cop solving a murder case involving aliens.
The good sheppard:hated it, long and boring as hell, could of been good with the actors but not so
The last king of scotland: great story about real life events (except the scottish guy was a make believe character put into real events that happened. The bonus features were very entertaining.
Hoffa: great story about Jimmy Hoffa and the extras were very good.
So there are just a few of my picks, we seem to have about the same taste in movies so I think this thread would be a good place to see other movies that we were not aware of.
