Endeavour Morse's affection for ale and whiskey is one of the character quirks Colin Dexter wrote into his detective in his novels. When John Thaw brought "Inspector Morse" to TV in the 1990s, audiences came to accept Morse and Sergeant Lewis' (Kevin Whately) regular pops into the pub to mull over a case while enjoying a pint.
Morse's habit was part of his persona in the original series. Its prequel "Endeavour," set in the '60s and early '70s, establishes that the detective didn't start out that way. But the years have taken a toll on Shaun Evans' Endeavour Morse, and as the three films that comprise Season 8 show us, his drinking habit is getting in the way of his relationships and his ability to do his job.
