Sins of the Show-Runner?
A commentator at the Tor.com discussion of The Middle Men passed along a "strong rumour" that Torchwood: Miracle Day was originally meant to be a five-episode series, but was expanded to ten, "so that Starz could get subscribers for longer".
Like any rumour, I take this one with the proverbial kilo of salt, but it does offer a credible, if not fully explanatory, hypothesis for the remarkably slow and inept story-telling to which we have been subject lo! these past seven weeks.
Less subtle than an average episode of South Park, the seventh episode is the best outing of the series so far. Or perhaps I should say, the least bad.
Immortal Sins at least boasts some action, some humour, some sex and even some romance.
On the other hand, the sex and romance is at best only as good as the merely competent fan-fic it will no doubt inspire, the action was counter-balanced by long, gruesome minutes of torture that would delight Mel Gibson and — of course! — a secondary plot and characterization that make no sense and which are in any case mostly negated by episode's end.
For skin, spoilers, stereotypes, structural analysis (and, yes, snark) see Mel Gibson comes to Torchwood or, The Passion of the Jack. Probably not safe for work.
