I just cannot miss this movies:
1. Korosu - Madness in Tokyo (http://www.newgrounds.com/portal/view/646322). Rare sort of madness movie, when enemy agents can do something and aren't just immobilized dolls. Just khaang epic.
2. Madness - Altered State (http://www.newgrounds.com/portal/view/646326). Interesting graphic style... and just good thing.
3. High-Speed Madness (http://www.newgrounds.com/portal/view/646310). It's...It's awesome. No comment x]
4. MAdness Impact (http://www.newgrounds.com/portal/view/646299). Very good collab with Sanford as protagonist.

All this movies were awesome, but there are others like REALM: Project 00X, AMA 2 and Madness Cleanification that were even better! :D

About some of this movies i have said in my previous newspost. In fact, i agree with you about Cleanification - comrad Gabriel did awesome thing.
What about REALM... I didn't like it because of total lack of original ideas. It was pretty booring to see =-_*=
AMA2 (IMHO) is stupid movie with dumb humor and bad animation. But, maybe, it's just my opinion.
