Graphics: D+ (You could've used sprites from some of the newer Super Mario games opposed to the old Super Mario sprites)
Style: C (This has been done before...somewhat, but the idea of a director's cut of the game is fairly sound)
Sound: D- (No music and limited sound fx, you should probably add music to this)
Violence: C+ (The violence level is reasonable and not too excessive)
Humor: B (Some of the scenes were very funny)
Overall: D (Although it's not the worst movie I've seen on NG about Mario, it's not as good as some of the good ones either).
