After last week's epic conclusion to the two-parter, we go for a what is a bit more of a romp, with the Timey Team on board a pirate ship dealing with a "siren" that is luring the crew away.
I'm not going to go into a description of the plot, which involves an alien spaceship, treasure and a famous pirate. I'll just go straight into the review.
The start is very promising, but then things go downhill rapidly. The pacing is off badly; this might have worked better as a two-parter. The dialogue starts to get a bit forced - this seems to be a pale imitation of Moffat's style and it shows. Then the bit at the end with Rory just walks slap bang into cliché. One note - if you're not breaking ribs, you're not doing it right.
Hugh Bonneville's Captain Avery is served badly by the script. Lily Cole doesn't even get an intelligible line and doesn't really add much to the story. Matt, Karen and Arthur all try their best with the material, but that's all they can do.
Nice try, but I'm going to have to give this a 5/10. The words "whole", "sum" and "parts", spring to mind.
Neil Gaiman's episode next week looks good. We'll see if my Doctor Who RP (The Triple First) ends up having its entire concept yanked out...
