The series mostly respects the original plot, showing occasionally good animations and emotional moments. However, it fails the challenge of adaptog the slow pacing of the game to a short series. It features poor dialogues, missed introspections, missed characterisations, too much screentime to secondary characters. It skims over some fundamental events, dedicating too long to secondary content, it overlooks the Kung Fu learning process of Ryu, it misses to enrich the contextualisation with important characters, and it features some embarrassingly designed scenes that weren't even in the original plot.
It's not a disaster, but I wouldn't recommend it at all.
