I'm just gonna say what i think:
Weird stupid intro.
Annoying music.
Fucked up color effect that seems pretty random and out of context.
All the effects seem very random, most of them are just annoying.
The slow-motion seems random, doesn't really fit the kills.
WTF was that outro?
The clips are from fucking Nuketown and they are based on luck, not skill (I know most motages/edits are lucky clips, but I hate that. If you play a lot everyone can be lucky).
