The SFII movie is pretty awesome. It still looks very nice, and the fight scenes are badass (they actually fight hand-to-hand instead of spamming special moves). Plotholes? Who cares, it's Street Fighter.
You can buy the DVD for $20 at an HMV or what have you, with the Japanese track on one side and the English dub (with the KMFDM music) on the other. You can also get the Alpha OVAs in one case for about the same price if you're so inclined (I only saw Generations, which was okay).
