Feels like this is another show that deserves its own thread, and given the nature of the show, I don't think it's fair to discuss in detail in the general TV shows thread, as it could give spoilers to those who still intend to watch.
Anyway, I finished up Season 1 this weekend. What a wild ride!
SPOILERS BELOW (I am not doing that super small font or anything like that)
For some reason, I had it in my head that there were 11 episodes, not nine, so I was expecting two more after The We We Are. That said, great way to end the season. I like how they left enough get out to where even when they all revert back, things will not be the same. Mark's outie and Devon will now know that Mrs. Selvig is his boss, Cobel, and he now knows his wife is alive (but was fired, so will not be at Lumon anymore). Helly's innie will now she is the daughter of Lumon's CEO on the outside. Dylan will know that he has three kids, not one. Irving will be shattered on the inside because he will know that Burt is on the outside and in a relationship. The four will be more determined than ever to get off the severed floor, but how will they accomplish that? Season 2 ought to be a doozy!
