3D animation is not within my field of profession, but I can say that the models look very grotesque and horrifying and are only animated slightly better than a SMG4 video, that is, every single character squashes and stretches.
I will however praise the fact you went over the 8 minute mark, something extremely rare in web animation.
Overall, I think this was entirely done on purpose and the whole point is that it's a shitty recreation of something amazing and everyone here is liking it because it's a shitty recreation of something amazing. I mean, how else are you going to get half a million subscribers on YouTube? Original content? Like that ever works. That belongs on Newgrounds!
