I put drama, 'cause you can put other genres into it - Dramady, Dramaction (I made that one up) etc. And the best movies need drama.
I care very little for Horror, it bores me. Unless it's truly fantastic (see Rec, 28 Days Later, Let the Right one In)
Documentaries are cool as long as they're David Attenborough.
Action, if it's mindless is crappy. With drama - win.
Romantic can be good if it has drama.
