Overrated...
I don't see what the big deal is about this series. Rob's animation is mostly tweened, and the only walking/running he does are 3-4 frame cycles. His sticks, set at thickness 1, are very ugly and his animating his choppy in general. In fact, it almost looks like you copied the animation style of the guy at stickdeath (I don't know who he is because I've only been there a few times and I don't like his movies either).
However, its not all bad. Your cinematics, voice acting, and plot development are pretty good and they are what keep this series interesting.
But come on, atleast try learning how to animate. Or maybe you should ask someone like Master Samus to do it for you. Now he would make a good Joe Zombie movie...
