I must point out, if you haven't seen the TV Show, it is not very related to the movie. I don't know which is more faithful to the original graphic novel, but don't go into it expecting the same story as the movie except stretched into a TV Show. It is very much its own beast and I love it for that. I couldn't say yet which I think is "better", they can both be very much enjoyed on their own without having seen either beforehand.
