Perfect!!!
I'll choose things to judge it on.
Graphics (sprites) - 10/10
The way you used the sprites were perfect, you used the right images at the right times. It was great use of it and it didn't even look bad when you moved them across a path or road. The movements actually fit the action unlike some other bad flashes. Greatest sprite use I've ever seen.
Sound - 9/10
You pretty much nailed it. The time you used it, the way you used it and the type of music and sounds you played made it really funny and interesting. I think it was great how mario and luigi had voices but very little. Even if it had text of what they were saying it spoils the fact that they never talk in the games. Good job!
Humor - 10/10
I almost laughed more than what I did with scary movie. Using those certain cartoon's (Mario, Dragon Ball Z and a bit of sonic) made great comedy. The race was just just that little bit idiotic that it's funny and Bowsers stupidity is pricless.
It's is like scary movie making fun of certain shows or movies. Great!
Story - 10/10
As I said with humor the choice of cartoons really helped the story and these certain scenarios fitted prefectly with them. I don't get sick of changing movies to see the next part of the story and I usually do with series. Fantastic!!!
Overall - 10/10
Congratz mate, you made the mona lisa of sprites.
