Sadly, less than amature...
This movie, needs a lot... And I don't know if I could do better, but here's what it needs...
1) Background, Look at it, Get something actually from mario
2) Funny stuff. What the hell was with the hang glider?
3) WTF was with the birds? That perticular part was extremely boring and not a bit funny.
Just some things you can add.
