What sets this film apart from others in the fighting-game-turned-anime genre us that the plot and character setup are especially important to the actual portrayal of the character. Don't expect to be able to jump into this film and like it, because you won't. If, however, you choose to watch it from the beginning and actually empathize with the characters, you will most likely enjoy yourself.
Street Fighter Alpha (the videogame) was the turning point of the street fighter universe because Ryu ceased to be the wandering, invincible (and emotionless) street fighter who is thrown into the plot by accident, and became the central character of the story, in a far more convincing fashion than Guile and Chun Li ever really managed in Street Fighter II. This movie is the expression of that story in film.
The fighting scenes are spectacular and the story well-paced, but in the end, if you're looking for the kind of popcorn-action flick that guys watch during frat parties, the original Street Fighter Animated Movie is much more your cup of tea (or beer). If, however, you're looking for a sensitive film which deals with the personal side of each of the characters involved, Alpha is much better.
