Mario + Golden Knights?
I enjoyed this movie, but was confused by the Black/Golden knights. They don't seem to fit into the Mario Bros. mythos. It was especially bizarre to see such a tacked-on idea in the midst of other, appropriate ideas, such as the use of the smaller airships from Super Mario Bros. 3 as the "rowboats" of the larger airships. Wario was a bit out of character, but at least it's an interesting interpretation. In comparison, the Golden/Black knights were completely out of left field.
They worked well enough for the purposes of this flash, I suppose. I hope to see future projects of yours with a tighter focus.
