I'm just gonna say what i think:
Weird stupid intro.
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).
