The second rule of Torchwood is, you should steal plots from other movies and TV shows, but do so in such a way that it feels compelling and relatively original.
The third rule of Torchwood is, make sure you throw something in at the very end which knocks everything out of balance and makes the show even more of an interesting prospect for the series finale.
And so, Torchwood started its final approach to the series end in two weeks' time with a fairly simple-enough plot to divert our attention away from the bigger storyline.
Someone (or someones) was going around kidnapping Weevils (those evil-looking subterranean creatures from episode one), and when the Torchwood team discovered a dead body in a dockside warehouse, Owen was sent undercover to infiltrate the life of a wealthy estate agent and get to the bottom of the mystery.
Meanwhile, Gwen was suffering from relationship problems, and foolishly told her boyfriend about the long-running affair with Owen, before drugging the poor bloke with an amnesia pillto make him forget what she'd said.
What Owen discovered on his mission was something much more than people simply kidnapping Weevils, but people kidnapping them for sport.
The rest of the episode was fairly predictable-enough fare, with Owen finding his way in to the heart of the 'Fight Club' organisation who were capturing the Weevils, then imprisoning them in a cage and taking turns at getting into the cage for £1000 a pop -- with the man who lasted the longest in the cage with the Weevil taking away the entire pot of cash.
And that included Owen.
But it was the ending which made the biggest impact on the storyline, by throwing a bit of a spanner in the works for the remainder of the series -- and if you don't want to know what happened, I'd suggest you look away now.
In fact, I'm not going to tell you what happened -- you'll either have to watch it for yourself, or figure it out.
Put it this way, I now understand why Burn Gorman was picked to play Owen, with his wide lips and sly grin...
