Kinda lacking in jokes...
Seen a fair few versions of this on NG but never get tired of the song.
Your characters are kinda charming.
The textured Mario Bros. sky was lovely.
The idea of plonking Link into the Mushroom Kingdom is cool, but it didn't really seem to go anywhere. I mean, we didn't see any particularly funny interactions.
And for the most part, I felt the movie was slightly lacking in jokes or visual eye-candy. Too often, it seemed like you were just sorta struggling to fill time rather than having a packing of entertainment.
