THE NUN is a cheap Spanish horror film about a group of teenagers being menaced and bumped off by the ghost of a killer nun. The version I watched (on Amazon Prime) had been badly dubbed into English. It's a slow and rather painful movie to watch, with 1990s-style stylings and a distinct lack of action. That's not so bad, but when there's little atmosphere to go with it then the whole thing feels rather pointless.
