I too fully enjoyed this particular episode. I didn't realize going into it that it would be a sort of self-contained story, but I got so lost in the narrative that I completely missed the fact that it doesn't really advance the larger "plot" of Dolores and the Man in Black and Bernard and all the others. It was so fluidly done that I didn't mind one bit that we'd put all those mysteries on hold. Very nicely played.
Woah, it's been 8 months since I've been here or watched the show but I fully agree with you!
