Awful
I'm not a complete retard, so I won't waste time making idiotic references to your personal life, but, I will say that this movie sucked. The only redeeming thing was that the sprites weren't as pixelated or blurry as I usually see (well, except for Giant Yoshi, but I'll let that slide because I know there wasn't any avoiding that)
For starters, the title is very misleading, there is no "battle" whatsoever. There wasn't even enough substance to qualify this as a Megaman vs. Mario sort of movie. If you're going to have dialogue, let it serve more of a purpose than to get "Uh oh, I die now." across. And for the love of cold, carbonated soft drinks, if you're going to have Battle in the title, put in a fight scene, a good fight scene.
