I enjoyed it. Rafe Spall doesn't quite convince me as a leading man and the story was a bit slight but if you like Jonathan Creek, and the idea of a cynic who wants to expose fraud and explain phenomena that many consider supernatural, it's for you. It's also very much an ITV period drama - two of the supporting female cast members were prominent in Downton Abbey - which is something I personally love. Shows like The Suspicions Of Mr Whicher with Victorian set design and costuming are always ones I gravitate towards and this is very much in that vein though set a good few decades later. It's certainly not as highly budgeted as some other period dramas but it does well with the resources.
I watched it ahead of time and skipped the credits! Mea culpa!
The credits were tiny and squashed in the corner on the broadcast version anyway so any of us not really, really looking would have missed his name - I only would have thought to look for Scott because of him mentioning it.
