Watch if you're into: Grumpy old detectives who are surprisingly smooth with the ladies; long and slow episodes that allow for multitasking (hey, sometimes you need something to watch while you fold clothes, catch up on work, etc.); and '80s and '90s British fashion. I'd also recommend watching this first before the spinoff starring Inspector Morse's partner, Inspector Lewis, and the 2013 prequel series, Endeavour, that follows Morse at the beginning of his career.
How many seasons? Seven plus five special episodes
Where to watch: Watch Inspector Morse on Amazon Prime Video.
