Don't agree.
Before I get off about how I don't agree lets rate the actual movie itself. It was an original way to get an unoriginal message to people. It's a sad movie in general (meaning the main character has a inferiority complex err I think). Great sound, fitted the flash perfectly. I would comment about the characters looks both Mario and that anonymous 3D rendered bald man, but I don't know what type of style you were trying to make.
Now thats over with, I don't agree with people having to stop making sprite movies at all. If they want to, go ahead as long as it's decent. I would perfer to watch a decently funny or good sprite flash then a crappy very carefully drawn out unfunny/cool drawn movie. I perfer plot quality more vs Eye Candy because Eye candy doesn't make a story, the actual plot does and the events that take place in it. Also should a person want to make a sprite movie why stop them? If they're not in it for the money then there isn't any harm in it.
