Eh.
It wasn't bad.
But it's far too repetative to warrent me to watch it again.
Even if all you do is change between 2 or 3 different cycles for the same character it would catch the eye a little bit better.
Without something different to catch the eye after something's been repeated for over half a minute it starts to get dull. Without the grenade bit and change to silencers around the end I wouldn't've watched through the whole thing.
