Crooked House

This is only available for a couple more days but it’s worth it. BBC4 gives us a reminder that you don’t need a big budget to frighten your audience, however jaded by CGI they may be. In this spooky drama by Mark Gatiss there are hardly any special effects, just a clever script and your imagination.

At first this seems just an entertaining throwback to those portmanteau films that stuck a few ghost tales together, added some kind of sinister, squinting narrator and hoped for the best – but the modern story that links everything together here turns out to be properly terrifying.

Can’t say much more without spoiling it – just watch it quick, and don’t answer that knock at the door…
