It's good, not great. I'll finish watching for sure because it's entertaining and not much else is out right now, but so far the editing, CGI, pacing, and plot leave me feeling kinda meh. For an HBO production it's underwhelming.
Edit: Yeah I don't think I can finish it. I made it to episode 5, which was basically just revenge porn that totally deviated from the "plot" if you can find one at this point. It just can't decide what it wants to be. It's all over the place. No use investing 4 or 5 more hours on this, which is sad because there is a lot of potential here.
