What the only or majority gender? It is mainly/only a girls party or a boys party? Whats the average age? A few suggestions would be:
You, Me, and Dupree
I love you, man
He's just not that into you
10 things I hate about you
Being more specific in the type of genra would help too. As far as with comedies, do you like intellectual comedy, dumb comedy, rauchy, etc?
