DH & I like gentle murder mysteries (Columbo being the best ever, but we also really enjoyed Midsomer Murders and Murder She Wrote), and we've been watching an old British show from the 90s on Amazon Prime called Wycliffe. It's got nice little mysteries that are wrapped up in an hour. No violence (on screen, I mean, obviously someone's been murdered, but we don't have to see it) or gore, which I like, and no extraneous drama about the detectives (which DH loves--he hates that stuff and refuses to watch Luther b/c it's all about Luther as opposed to the mysteries).
I wish we could find more like this. We've been through all of Midsomer Murders, all of Vera that's available off of BritBox, all of Murdoch Mysteries, all of Murder She Wrote, as well as several others that I can't remember at the moment. Can't bring myself to pay for Britbox b/c, ugh, another subscription? We've already got Netflix and Amazon Prime.
