Masterfully done.
(To anyone reading reviews first, sorry about the spoilers in this one!)
-Graphics: That pixel-perfect detail in the menus just baffles me. How do you do that? In FLASH, even? ...not to say the movie itself didn't look good. I loved the camera's parallax "scrolling" in the last arena. 9/10.
-Style: You know, I never really get what this review box means by "Style." But like your comment said, the animation is smooth as can be. Should the mention about the "camera work" go here instead of Graphics? Oh well. 9/10.
-Sound: Good choice of music. Although, I feel there could've been some new sound effects. (I noticed the ones that were there, I just felt the old "biff-bap-whap" sounds were starting to get a little old). 8/10.
-Violence: On my scale, a person getting broken into pieces without blood shown is simply worth 2 points here. 2/10.
-Interactivity: One point for scene select. 1/10.
-Humor: One point for Akuma shattering Scorpion. I don't know why, it was just funny.
In my days on NG I've never seen a sprite-based flash with as much polish as MK vs. SF. Ryu dodging the hooks somehow made me think of all those manic shoot-em-ups I play, weaving through mazes of bullets...anyway, let's just say I enjoyed this film enough to watch the battle twice, and leave it at that. 9/10.
