Where to begin with what could be fixed up about this submission... Well, first of all, this movie could be much longer. Sometimes long movies suffer from being overdrawn, but it might be an advantage in this case. Perhaps add some more to the battle scene? Or have Anon spout more memes before Pico loses it and kills him.
Also, I don't exactly care for the single particular meme you picked for Anonymous' one line before finding his ass handed to him. Not so much that it doesn't work well in the movie, but that's just not one of my preferred memes.
Now for the good points. As short as it was, the animation was better than a lot of the stuff I've seen on NG thus far, although it was far from perfect. And it was in color and had sound, two things that many movies of this length, for some reason, lack. So it sure isn't the worst movie on Newgrounds, but it's not the best either. It's not quite, in my opinion, even average.
