I'm actually really surprised that the fangirls responded so poorly, because that episode really was a love letter to the internet. Just about the entire 90 minutes was a direct response to the Tumblr People (#SherlockIsAlive), and Holmes actually has a girlfriend who actively encourages the two to be together.
After informing Watson that he's not dead, he then just randomly tells everybody else, because this whole suicide contrivance was a narrative dead end, so they just plowed through someone's house. The show spends at least half the run time mentioning and then dismissing possible ways Sherlock would have faked his death, to absolutely no end. You wanna skip explanation entirely? Fine. But there was never a 20 minute scene where Vincent and Jules talk about the various things which are not in the briefcase.
Hearing and dismissing rumors that Sherlock is alive, DI Lestrade (yes! THAT Lestrade!) is smoking in a parking ramp when a voice from the darkness says "Careful! Those things will kill you!"
Thinking he could probably do worse, Sherlock later says "Killing me? That was so two years ago!"
Later Sherlock learns about this strange thing the Hu-Mans call love, and there's a hilarious punchline about an off-switch.
This was pretty much a CBS police procedural with English accents.
