Just saw it. I liked how the cast suddenly learned how to act in this episode. Excluding Walt and Caesar. They sucked. This episode was pretty ugh overall. On DEATH BY SPIDERS and "I DON'T DO TACO NIGHT!" levels of meh. Locke's visits and his death were talked about so much that when stuff happened it was like, "Yeah. Whatever." TBH, I think Locke is a pretty boring character.
316 is my favorite episode thus far this season.
