Torchwood does the Texas Chainsaw Massacre, only in rural Wales and without any chainsaws.

The cold open is a really well constructed, little slasher movie scene. I thought it was very good and grabbed my attention immediately. The splitting up of the group and Gwen getting injured early were both very effective ways to raise the stakes. The episode does a good job of building and maintaining a creepy & tense atmosphere throughout.

The episode sets this up to have a sci-fi/supernatural creature doing all these killings. So the reveal that it was just the human residence of a creepy little town, who every 10 years or so murder people who pass through for their cannabilistic pleasures seemed like it might underwhelm at first. But the mundane origins of our killers arguably makes this episode scarier. Plus Owen Teale gives a fabulous performance as the leader of the cannibals. The way he explains why the townsfolk kill as being "Because it made me happy" was genuinely chilling.

I really like this episode. Doing a take on a horror movie seems like a fun use of Torchwood's ability to be more 'adult' than Doctor Who can be. I wouldn't want it every week, but as a one off this was a refreshing change of pace.
