I watched this show over the course of maybe a week, basically binging it now that it's all out. I've found that I enjoy shows better when I can cruise through them in about a week or two, rather than trying to analyze episodes week-to-week, at least when it comes to serial shows. Episodic TV is different. I don't care about the week-long wait then. But I don't think you can -- when it comes to what are essentially miniseries shows -- evaluate the show on an episode-by-episode basis. That's like saying "Wow! Great first chapter to this book but, hmm....Chapters 2-3 kinda lost me. It got way better again in Chapter 4, though!" I don't read books that way. I just, you know, read the book and then evaluate the whole when it's finished. (If I worked as an editor, it'd be a different story.)
Anyway, that's how I approach shows like this, and on that basis, I loved it. Not every episode was a home run on its own, but every episode worked to tell a complete and very entertaining and compelling story. I actually wish it had been a little bit longer, but I'm ok with this being kind of the tee-up for other adventures.
