Echoing a number of posts above, yeah, this was the first episode this season that really lost me. They had built up so much good will, but then this episode, with so much offing of main characters in such flippant fashion (really, we're "killing" Maeve again???) was such a turn-off for me. Especially since we know Halores will no doubt be back (there's still that shot of her from the trailer, at Hoover Dam, firing a gun - the gun I assumed Bernard left?), and I'm sure Maeve will be as well (really, it's comical now how many times she's been resurrected). But Bernard feels like he's gone for good (though I assume he'll reappear digitally next episode/season), and I was always hoping the real William would somehow break free of his cryo chamber, but that whole thing just felt like a prolonged tease now. Too bad, because I loved both of those characters still being part of the real world, while the remaining pieces just don't do much for me. And even if everyone who "died" this episode returns next week, or next season, we've officially reached the point where it's, like, copies of copies of copies of nearly every host and human remaining in the main cast, and I just don't understand how the filmmakers thought that strategy would make for continued character investment on the part of the audience. Especially when it comes to Delores/Christina and whatever the hell reveal that was, which fell so incredibly flat among all the other "surprises."
That said, because I was so let down by the episode, I went back and watched it again a couple nights later, just to try and examine why it missed the mark so much, and it *did* play better the second time around. It's still not at all what you want from the penultimate episode of a season of a show you love, but it does work a lot better when you know what's coming.
