Watched via Stan last night the one off Sherlock special episode The Abominable Bride, and, as much as I intensely dislike Steven Moffat's work on Doctor Who, I have to say I thought it was pretty terrific.
The episode is copping much criticism, and I don't really understand why. Even a significant proportion of commenters at The Guardian (home for all Moffat fanboys and girls) had trouble with it, yet I think part of the problem may be that some did not think hard enough about what the episode was doing. (Which is a little odd, because some of the criticism is along the lines that it was being "too clever by half".) Maybe it is just attracting too much over-analysis: can't people simply enjoy it for its fast and witty dialogue, effective spooky scenes, and fine direction? Or - another theory - it rated very highly in England (unlike the badly declining Dr Who ratings) and some might have been viewing the show for the first time, in which case, yes, it would make little sense.
But if you are going to go the "analyse it to bits" route, I think one person at The Guardian probably had it right. I'll link to his or her post once I can find it again!
