You need to learn how to take fucking criticism.
Seriously, shut the fuck up with all this "OH THE REASON ITS SLOW IS BECAUSE YOUR COMPUTER IS SLOW" or "YOU HAVE NO IMAGINATION". Look dude, bitch, whine and complain that people don't like your movie all you want, but if you really want to get better at animating, then quit with all of the damned excuses. People write reviews to help you, not to make your life a living hell and torment you. When someone says "I didn't like this movie because *insert fully constructive reason here*" it doesn't mean "You suck go fucking die".
Now that I've gotten that out, now for the real review.
The movie just starts out of no where, no intro, nothing to explain the plot at all. It just starts out with some guy climbing from a trap door. There are a lot of extremely awkward positions that you have the main character in, ones that would be pretty uncomfortable and impossible for an actual human being. It looks like he's trapped inside an original box. The only animation is the character sliding across the screen, there is some feet movement but that's about it. Have him run through some halls then an extremely unexpected choppy ending. There was like, no thought at all put into the ending. It looks like a three year old got ahold of the computer and randomly placed Madness sprites everywhere.
That is really it, the movie its self was only 10 seconds. My suggestion, study Madness movies, good ones at least. Just watch them and focus on how the author animates the movement. Overall this looks like it was made in like 5 minutes. Spend some time on an animation. Don't just shit out a movie every few days, because in truth, no one really wants to see this. This is what gives good Madness animators a bad name. This is what basically ruins Madness. If you still want people to criticize your movies, upload them to a swf hosting website and link to it on your userpage.
And remember, stop taking criticism like the biggest damn insult.
