It started off well, but then it went down hill. By the end, I just didn't care about any of the characters - I just wanted it to be finished. It didn't need to be so long, honestly. If it was trimmed to 10 episodes with a more concise plot it may have been better, but it dragged for so long.
It could be cool to wait to watch until ep.10 or 11 releases, binge it, and be here for the finale.
