You can't make a good movie by not using gore.
Now I don't only like a movie because it has gore or obscenities, thats extremely shallow. But there was nothing interesting in that movie. The drawing and the music were very well done but some kind of plot would be good. There's nothing WRONG with gore or comedy. It's what makes Newgrounds content different from bad daytime TV. So yeah go with something deep and meaningful as long as it's entertaining as well.
