Yeah, the plots are mostly either a) blatantly obvious to anyone with any survival skills/street knowledge/genre awareness, or b) completely impossible or nonsensical as stated (with a side order of "ludicrously overcomplicated and way too unlikely to actually work in RL conditions. Which is really disappointing. The 'cab driver as killer' thing was in the original Doyle story, so I wasn't surprised either way, but the original Doyle story actually had some complexity to it other than "serial killer preying on random victims", so there, it worked. Actually I think a point-by-point modernization of the Doyle stories would've been a lot more interesting than what Moffat and Gatiss are doing, even if it lacked surprise for the Doyle fans, because you can really tell where the Doyle leaves off and the inferior Moff plots take over. And to the extent they are adapting Doyle, they're doing it by taking all the interesting and clever out and leaving in the cliches...

I am absolutely sure I was not the first person to do the Princess Bride post-ep! Because it was just so blatant, OMG. Did they actually expect us to not immediately assume there was no right answer? And of course in the Doyle story it actually was a random chance left up to God, but see again with Doyle putting complexity and motivation in...
