I spent the whole episode (because I had enough vague memories of previous tv versions to know what the end was going to be, just from the title) thinking "this reminds me of something" but it wasn't right until the end with Sherlock watching John at his graveside that I realised it was the Doctor, because faking his own death is something I expect far more from Sherlock than the Doctor and I'd kind of forgotten the Doctor had done it!

Plus, oh god yes, Sherlock/Moriarty is totally Doctor/Master, but again that's something I grew up knowing. *g*
