Anyway, I'm not going to do a full-blown review because this series is so short, anything too descriptive might be too...spoiler-y. What I'm going to say is this: If you had your childhood destroyed by the 1994 live-action Street Fighter movie, this rebuilds your childhood and takes it to the greatest of heights.
At first, I had my misgivings about Street Fighter: Assassin's Fist despite seeing a very promising trailer in its Kickstarter page. But private backers resulted in it being pulled out of Kickstarter (thank goodness!) and I was not disappointed. The casting was perfect. (My first thought was: Oh, wow, they found a Ken who actually looks hot even when he seems like he is in dire need of a bath.)
Street Fighter: Assassin's Fist revolves around the origin of Gouki and Gouken, plus the development of Ryu and Ken's relationship as brothers-in-arms. If you're not after the story, which, by the way, is as close to the game as it can possibly get (with a few compromises here and there), you'd have lots to enjoy from the fight scenes as well.
