If you want my honest opinion....
I dunno about this being TV material..maaaybe on Adult Swim..but to me it seems like it be better to be just a web series.
the actual animation....wasn't that great...wasn't very fluid..looks like most of the movements were done with just a few motion tweens in Flash or limited animation in After Effects...it just wasn't that impressive....Then all the stereotype/cliche characters..some of them were funny, like the nerd yelling "lvl 10 zombie" but some of the others were just kinda "ehhhhh" not too funny, nothing very original. The idea of zombie fighting is fun, but I overall I think the animation and writing needs to be better. I know it was just a promo, but it just didn't quite do it for me s'all.
