Inspector Morse is outstanding. A little quirky but that makes it. The follow up series — Inspector Lewis (Further cases of Morse’s sgt. is also good.)
I really like Endeavor which is early Morse.
John Thaw was excellent in Inspector Morse.
Another show of his was The Sweeney. First rate action.
Having seen a few Morse shows, there’s a hunger to see more. Like the mystery, and the crime inspectors who tend to be a bit quirky are always entertaining. ie.... Murdoch Mysteries, Murder in Paradise, Monk. All three are always an unexpected treat.
