Nothing was surprising. Of course I dug into the Internet theories.
I have completely avoided all internet coverage of/reaction to the show and have watched the first 9 episodes within a period of 4 or 5 days. With no outside influence and given that I haven't spent too much time—outside of time spent watching it—thinking about what twists may be laying in the weeds, I will say that some things have been fairly easy to predict. There were some general ideas I knew were going to unfold but exactly who, when, why, etc., was less obvious to me.
Definitely looking forward to the finale and at that point I will start digging into the discussion/breakdowns.
