Half the issue is talking heads, the other half is zombie attacks on London. The zombie attacks work better. Fabbri’s not suited for talking heads, especially not with his characters boldly edged, standing out against the backgrounds. It makes it seem unreal and artificial, something a talking heads scene should never be.
The exposition–it’s Holmes, Watson and Mycroft sitting around and basically recapping what the reader already knows and what Holmes and Watson don’t yet–is a little tedious. The payoff comes with the zombie attacks, but even those are a little… restrained. There’s not the en masse zombie attack yet, only the hints of it.
The concept for the series–the tagline–is better than Edginton’s script, unfortunately. His Holmes is a pop culture figure, not really Conan Doyle’s consulting detective. He’s playing to zombie fans, not Holmes aficionados. In fact, he’s ignoring them, except for occasional callouts.
