As you know, I'm a huge fan of John Wyndham and the BBC have just made a new adaptation of his novel The Kraken Wakes. The time period has been updated, but it still has that fabulous 1950s B-movie feel to it.
It was adapted by Val McDermid the crime writer, who apparently has always been a fan of Wyndham, and she's done a bloody good job. Atmospheric, suspenseful, and scary; just like the novel. Absolutely fantastic, and well worth a listen.
