Comedy - Slacker stories, romcoms, miscommunications, stupid situations and satiriffic put-ons. LOL in your cu-bic-le.
Horror- Dark, twisted and ugly tales pulled with pliers from the bloody minds of very nice people.
Drama - Reminding us that dramatic art is the imitation of an action that is serious, a peak into the vanity of life, with incidents arousing fear, pity, beauty and the sublime. In under 25 minutes.
Animation - Bored, restless students who made flip books and doodles are now doing the same, but in 24 fps. CG, hand-drawn, psychedelia, claymation, stop motion, anime, and even black-and-white. Just don't call them cartoons.
