I am disappointed at your previous responses...
Seriously, these people are just trying to help, it is very uncalled for to just erupt at them in their faces..
Now here, is a review made up of constructive criticism,with no insults, only tips, I do warn you that this is a negative review, but hey, you can't always expect EVERYONE to like your movie, well let's get started.
At a first glance I see that this is more along the lines of a test, which belongs on Spam the Web, or some other simaler site. But since it was Madness day, I suppose it was alright.
As for the animation, I would say bad, but with potential. Some of the movements were choppy, while others were kind of smooth. You should practice giving your characters a bit of lean.. As in when they fire a gun, their body moves back a little, you had them to where it was like a statue, and honestly, if you took more time on this, this would have been much better. I liked the whole "elevator thing" because it was pretty clever, but you didn't make it clear that his head was sticking out of the door before they closed, because if he is inside of it, the doors wouldn't take off his head.
The blood animation for that part was badly and lazily done, like you just took the paint brush tool and scribbled a bit, which is BAD. Add more of a spray like animation, like take the hose or something, and watch the water and notice how it sprays, not just sloppily moves down slowly.
I also noticed that the character that got shot has two right hands, go watch some madness movies, and then you'll discover that there are different hands. He also fell really weird, when making him fall, you shouldn't just select his entire body and rotate it to the ground, animate each individual part different, add flow. And when he falls, add a very small bit of a bounce.
Over all this is bad. But you have potential, just TAKE MORE TIME ON YOUR MOVIES. Time is one of the only things that can make your movie a whole lot better. I can understand your rush if you had to finish it before madness day and stuff, but now you have a year, so work on something, and work on it for as long as you can too, if you finish it early, then take the time you have left for your deadline (if any) and add more finishing touches to it, like frames, effects, sounds, animation..
If you are offended by this constructive review by any way, then please leave Newgrounds until you learn that no one is perfect, and there is always room for improvement. People review your movies with a low score for a reason, no one is trying to be mean, they are giving their own opinion, and there is nothing you can do about it, because YOU decided to post it on this site. Whenever you post something, don't just expect solid 10's everywhere.
That is all I have to say. Don't take this review as offensive, because none was meant.
