Pretty good
Overall this flash was very well thought out.
The part that interests me most about the entire thing is that even though 90% of the second half of this video is nothing but senseless gore, I wasn't put off by it at all. I was actually -more- interested in it simply because after the first 2-3 gorey, sick deaths, I wanted to know how the main character would top himself. I won't spoil it here, but the final death really does top them all.
9/10, good sir. You deserve it.
