I just watched the first episode of Jekyll and loved it, of course, because Steven Moffat's the kind of writer I'd kill to be like and I wrote my thesis on the source text.
But, even though I really like James Nesbitt in the role, I did spend my entire time thinking, "John Simm could act the hell out of this scene. And this one. And this one. Infamous John Simm Crying Scene! And this one." Which is a shame, I think. Because, once again, James Nesbitt is very much of the great.
I wonder if there was ever a chance of having John Simm in the role. Sigh.
