A kind of glossy rehash of all the Dracula's Castle tropes gave way to a genuinely impressive recasting of Van Helsing as a Dutch Nun (actor Dolly Wells). Sadly, after the Count arrived in Britain, things deteriorated as only a Gatiss/Moffat production can, with a surfeit of pompously, over-dramatic, pot-boiling ideas all crammed in as a substitute for a genuine resolution. I felt optimistic after the first two episodes, apart from the last minute of episode two which signalled a change into something closer to Sherlock or Dr Who.
