Realistic plots. I’m not a big fan of ultra-happy or ultra-dramatic/sad plots. :| Far-fetched plots are just too fake for me (i.e., The Matrix 😛 LOL, I’m just kidding, Hector).
I also like dark movies—preferably, dark horror films. Original films are also interesting. Basically, I like something out of the ordinary that maintains its sense of reality. You know? I hope this makes sense. =\
