I did not love this episode. It was... difficult... so that's part of it. But I also think it could have lost 10-15 minutes of recapping.
SPOILERS
We are shown a flashback of the ultrasound, and then Laurie has to fully describe it too? I'm sorry, but how could any Leftovers viewer have possibly forgotten that scene? And the pills. Kevin Sr. reminds us that the dog's pills were strong and knocked him out, then we see Laurie staring at the empty pill bottle, then Laurie exchanges a look with the dog (which I liked), then Laurie tells the dog what she did (which infuriated me... we are not dumb viewers, so why put a button on it?), and then finally Laurie explains what she did to Kevin. That is FIVE explanations for this one event.
Perhaps more importantly, there was a lot of emotional exposition that I wish had remained subtext. Too many one-on-one conversations just draining that subtext away, especially the one between Laurie and John. (Laurie's talk with Kevin was pretty good, though, mostly.)
And in general, this one needed a heavier Lindelof rewrite. Not really up to par. Felt much more like Season 1 than 2 or 3.
There were things I loved about the episode. But I suppose my expectations are sky high right now.
