I've been meaning to recommend this: the BBC series about the early career of the detective we know and love as Inspector Morse from the series starring John Thaw in the late '80s and through the '90s. This is the second season, and there's only one episode left, so it's almost not worthwhile for me to mention it now. But I'm doing so in case there's anyone who liked the old series and hasn't given this a try.
"Endeavour," as fans know, is Morse's first name, which he detests. The show does a pretty good job of presenting young Morse as a believable version of old Morse. There are lots of nice bits for those who know the old series, showing the development of certain familiar Morse quirks--surprisingly, in the beginning he doesn't drink at all. But more than that, it's a good series of mysteries in itself, and would be even if you'd never heard of the others. Morse is a subordinate to Chief Inspector Fred Thursday, who is a strong character in his own right. The acting is excellent throughout, as we expect from the BBC. Ok, the plots are sometimes a bit far-fetched, but you have to overlook a certain amount of that in most mysteries.
The first episode of season 1 is available on Netflix, but for some reason the others aren't. They are on Amazon, which makes me worry for the future of Netflix. The most recent episode, "Sway", is still available for online viewing ("for a limited time"). And there's one more coming this Sunday. Each episode stands on its own, and you'll miss very little that's essential by watching them out of order. More information at PBS.
