I suspect that someone else may have already mentioned Steven Moffat's mini-series Jekyll, but I don't recall you having mentioned it here, so I am doing so. I very much like most of the dialogue, the pacing, the cinematography and James Nesbitt, though there are perhaps four shortish bits which I see as being clumsy and/or overacted. That said, I think that you've said that you can bounce off of 'clever', and there are a few plot/ethical decision tree points which could drive one batty if one refused to run over them at speed, so this isn't an unreserved recommendation.
