How to review a story that's just an obvious lift from a well-known fairy tale?

This one is a slight facelift to The Three Little Pigs, of course, with Sontarans taking the place of the pigs, protecting themselves with leaves, wood and a power plant against the wolf, er, Rutan.

It's told decently, with some fleshing out of the Sontaran characters, and if you want a fairy tale re-written with Doctor Who elements, this one's not bad.

A fun take on The Three Little Pigs that instead of teaching about building materials, teaches about battle strategy. This is definitely something I can see being a fairy tale told to time lords, and I like the way they've twisted a classic here.
