Torchwood: Instant Karma

Tosh investigates a series of mysterious deaths in this rather routine Torchwood offering. We're explicitly told in the pre-title sequence what's going on, so the mystery is around how she's going to stop the killer rather than who he might be or how he's doing it. This makes the story rather more leisurely than it might be, much of it consisting of Tosh trying to befriend the killer and get him to realise what he's doing and the effect it is having. As a result, things only really move forward in the final segment, and the fact that we know what's happening robs it of much of the tension.

Having said this, it's far from a complete loss. It's well performed, and written with sympathy for the characters that Tosh encounters along the way. In part, it's a story about the frustrations of everyday life, and the killer succumbing to the temptations that his ability creates for him. But Tosh doesn't get to do very much, and I got the feeling that she's in this one because the plot wouldn't have worked with the other regulars at all, rather than because she's a particularly good fit.

There's an interesting theme of what a regular person might want to get away with if they could, but it's too slow for the story to be as engaging as it might be.
