That depends on the guy I feel and and type of movie that you want to watch.
If you want to watch a comedy. The yes Man, and The Hangover is good.
Romance. A Walk to Remeber, Titanic, and Phantom of the Opera is the best!
If your in the mood for a scary movie, I belive the scariest of all time is The exorcism of Emily Rose, it is terrifying! Always fun to watch a scary movie, because you can cuddle up next to your date.
