Impressive over all.
I have to agree, that generic madness is getting somewhat old, but it will always be entertaining to some degree. I was rather impressed with the improvement you made since number 3. I don't mean to be rude, but I never even sat though the first 3, but i surely watched this whole one. It was an overall impressive tribute.
A few things to work on:
1. some movement was still a bit jerky
2. there was no sound during the chainsaw part exept music and hum of the chainsaw
3. i would like to see some more unique characters implemented...the eliminator looks a lot like hank, but he still pwns.
