We've seen it all before: he is an ex-cop who is now a hard-drinking private detective, and he is also a cynical tough guy but who secretly has a big heart and reads a lot. Even the Jack Taylor name itself is a very common name. Still the show is so good, you'll never see it as clicheistic. I dont know its secret; maybe it's the amazing chemistry between the character and the actor, maybe it's the good source materials (the novels). Anyway, it got me through the COVID madness and lockdown and that's something.
