Better than others
Graphics: Bodies were good. Heads should have had a 3/4 view. Blood sucked. wounds werw worse. Backgrounds were OK. The animation wasn't choppy, but it looked like it was tweened. Too many movie clips were used, too.
Style: No real plot and it's the same basic, find-and-kill-parody-style Madness. Also, humorous kills are getting a little old now, especially when done bad. Only if they're funny, I'd give 'em a good rating.
Sound: I dunno. My speakers ain't working, but I'm guessing you did a good job.
Violence: High kill count, low quality or cliche deaths.
Interactivity: Only a play button? Come on!
Humor: Not funny at all.
Overall: Your tribute was much better than many others. It's funny how people submit some crap like Madness: Counter Assault, but they don't submit other high quality videos like Madness 1337.
