Brilliant. Not quite as brilliant as Get Out, I thought, but my son was completely bowled over by it. Properly scary in a classic horror way - all the boxes are ticked but it's classy rather than cliché. Also very funny. Its real strength is the main characters, who are well rounded, well written and very well acted. You really feel for them.
I'm not going to say any more about it because spoilers - tbh, I think they already gave away too much in the trailer. But fortunately there's a lot more to it.
