So any of you guys watching this?
Personally, I think it's brilliant. The acting, dialogue, symbolism, and general visual tone is amazing to me.
I also have fun reading all the message boards about crazy theories. Many are, of course, off the mark (not that I know what will be revealed in the final episode, but all the theories can't be correct), but I think it's a testament to how well the show is done that there are so many different theories that are, in some way, supported by evidence in the show.
It's also really clever that a detective show, which is primarily a character study of two characters, is causing hoards of fans to dig deep for little clues and details to support their theories. And in some cases, to twist the clues to fit their own narrative (which is something that is exactly advised against in the first episode). The show works on a meta level in a lot of ways.
