I wasn't sure what to expect, so I decided to watch one full episode to decide whether to keep watching or none. After watching Episode 1, I was hooked. I would say the first 8 episodes made this seem like my favorite series ever. It had so many different dimensions; emotional, philosophical, futuristic, that just made it seem like a true masterpiece.
The last 8 episodes I would say were more action packed and less deep than the first 8, so I would say I preferred the deep meaning and insightful plot of the first eight, but still good.
All in all, I would say one of my favorite series of all time. And if you consider only the first 8 episodes, possibly my favorite of all time.
