This review at UPROXX by Andrew Husband is worth a read. It's an honest take on the merits of Houdini & Doyle by a regular television watcher and critic. It also contains a few choice insights about how the show has been rolled out here in the U.S., including this quote from creator David Titcher:
“All my friends hadn’t heard of it unless I’d told them about it,” Titcher admits. “We’re really trying to get the word out, because Fox has thrown us into the deep end and we’re hoping we can swim.”
There are only two more episodes of Houdini & Doyle left (including tonight), but you can watch all the past episodes at FOX NOW. Links to my reviews can be found at my Episode Guide.
