I binged the whole thing in one sitting over the weekend.
All in all - and I can't believe I'm saying this - I would say this is my least favorite thing directed by Cuarón. And that's not because it's a bad series, but because he's just better when he's directing movies and there's a tighter storyline that doesn't try to pull in several directions at once.
Without going into spoiler territory, I'll just say that there's an element of the "unreliable narrator" somewhere in the whole thing, and it leads the viewer sort of astray, except for me, it kind of didn't, because I could tell that it would just have created a gigantic story hole if the things that we were being told were really taken at face value. And Cuarón is just too talented to let
that big a story hole just sitting there, unnoticed.
But when we get to the "reveal" of what really happened, it still doesn't quite add up 100%, I think - there are a lot of things that don't make a lot of sense, even when looked at from this "new" perspective, character motivations that aren't believable, and other minor problems with that narrative.
I'm not familiar with the source material, but I'm just going to assume that this was a relatively faithful adaptation, and that the problems inherent with narrative consistency were there from the beginning.
Having said all that, there are still some pretty good performances in here, and it's kind of awe-inspiring to see how well Kevin Kline does playing a Brit - I'm not going to say that I completely suspended my disbelief, but I stopped thinking about whether or not he was doing a good British accent.
Now that it's done, I really would hope Cuarón doesn't continue working on TV series, he's better as a filmmaker and hopefully now that he's gotten this out of his system, he can go back to directing feature films.
