The sequence - in which the pair get booted out of increasingly scummy eateries, eventually landing on the street - was the first time in the episode that Sherlock reached the potential of its first couple of seasons.
Similarly, the interplay between the two as they try to defuse the bomb in the train carriage made for an absolute cracker of a scene, with "the off switch" providing a brilliant laugh and a great conclusion to the episode.
The production seems to be in top gear as well, as this was one of the best looking episodes of Sherlock to date. An imagined explosion that destroyed the palace of Westminster was exciting to behold, Sherlock's speedy motorcycle rescue was as good an action scene as the show has done, and the various visual flourishes - text messages appearing in mid-air, to name one - were seamlessly integrated with the action, less of a distraction than in years past.
This was a great return for Gatiss and Moffat's wonderful series, and The Empty Hearse would easily have been the best episode of the show to date, if not for the rather lucklustre handling of Sherlock's apparent Season two suicide.
I think my main problem with the explanation is that the episode handled it so wishy-washily. I can understand why Moffat and Gatiss, and co-writer Steve Thompson, would want to make a few nods to the massive amount of speculation online - my favourite being the laughable fan-fiction styled version in which Sherlock and Moriarty plot the scheme together then make out with each other on the rooftop - and make it feel like Sherlock's death gripped the public in-show.
But playing out three or four different scenarios and theories over the course of the episode made it feel a little like the writers couldn't decide which explanation they liked better, and figured out a conceit in which they could film them all.
Assuming we can take Sherlock's on-camera confession to Anderson as true, the eventual explanation - as I understood it: Sherlock jumped off the roof onto a giant airbag, used a corpse to appear legitimate, then switched places with the corpse and used a squash ball in the armpit to suppress his pulse after Watson was knocked over by the cyclist - was fine, if a little similar to many of the theories going around after the second season concluded.
It just lost some of its power because of the multiple scenarios we were given and the focus on the dynamic between Sherlock and Watson. Heck, even Watson was more interested in why, as opposed to how, Sherlock did it. By the end of the episode, I suspect most viewers at home were feeling much the same way. And if that was the point, then bravo.
As I say, a great return for these iconic characters; The Empty Hearse finds Sherlock (the show), and its writers Mark Gatiss and Steven Moffat, in fine form. It's just a shame they bungled the resolution of the only major Season 2 cliffhanger.
