I was a bit surpised
I'll be honest, as soon as I saw the words Mario, Sprite, and short, I was looking for the blam button before the movie even started.
Fortunately Newgrounds doesn't let you push zero until you've had the movie up for a while, and the movie wasn't as bad as 90% of the sprite junk that never makes it past the review. In order to help save projects like this from a blam, I would suggest putting a picture thumbnail up, and giving it a title something a little more creative than My Mario Sprite Short, so people will know it's more than some 6 year old kid making a 5 second flash during school lunch.
My tips for improving future movies, add sound effects, try to make more of a concrete plot, and avoid overuse of gags like the old man from Zelda hanging from the wall.
