Because Hollywood made it, that's why. The Tekken movie is terrible—something even Tekken's developers conceded. In an effort to make good, Namco is releasing Tekken: Blood Vengeance, a CG animated feature film.
The picture is being helmed by Youichi Mouri, who directed Tekken 5 and Tekken 6: BR opening cinematics. So if you like those, you'll probably like this movie.
The movie will be out this summer in digital 3D.
