As a flick, it looks cool.
As a continuation of Mass Effect, I don't like how it looks. It's too anime-y. What I saw there was an action anime, extremely exaggerated and unrealistic. One of my big loves of Mass Effect is the lack of the one man vs one army concept. Shepard always made it a point to say he couldn't win by himself, and that he was a driving force for sure, but not the only force to speak of. Several of the scenes showed one guy pulling off the one vs one thousand stand off maneuver. I'll watch it, but I doubt this will do the series any justice whatsoever.
