Wonderful episode. I loved the humor, the Freeman/Cumberbatch rapport, the multi-explanations (I'm not entirely convinced what Sherlock told Philip was true), John's strong reaction to Sherlock's survival as well as everyone else's varied reactions (although it's too bad Donovan wasn't in this episode), and even the meta references towards the fans (including Sherlock/Jim shipping). A little light on story, yes, but the emotional resonance throughout the episode made it worth while. I also loved the sly Moffat Doctor Who reference ("I believe in Sherlock." "Yeah, but that's not going to bring him back.") and how Philip has gone completely off the rails, batshit insane.
