I think your clockwork plots are still there, but they are adding in a more "American style" of character development, if that makes sense. I feel like, in the British shows I watch, the character development is central because it works its way out in a very intricate fashion over the run of a series (season, for the Americans) or an entire show (series). In that way, it seems that British character development feels more organic, and the plots can be somewhat secondary to understanding how the characters got where they are. American dramas seem to be the reverse for me, with sometimes very tight plots, but characterization that can rely on a single exposition supposedly explaining the actions of the character during that episode and then perhaps disappearing later (unless that exposition is supposed to be a big theme). I think that general difference is the difference for me between Sherlock and Elementary.
So this week they're supposed to be doing some riff on Hound of the Baskervilles. I don't know if I'm excited to see it or terrified that its going to be a mess.
It's very interesting to read that explanation of things. I guess because American shows have so many more episodes and very often have larger writing teams.
