Would I like this if I liked Insp. Morse + Lewis?

The universe of Britcop tv is quite wonderful. I don't think Frost lost too much over the years. It's no coincidence that Frost and Gently kill the spouses off in the first episode. All the shows typically have detectives with very little home life. Midsomer is the exception but their home life frequently contextualizes the mysteries. These dedicated truth seekers are flawed in a way that makes them better cops but loose canons that cannot be promoted.
Frost doesn't have a problem with drink but he's continually eating humble, unhealthy food along with that Damn Tea. His being homeless for several episodes highlight his lack of conventional home life.
The Britcop shows that feature female leads always have more personal Sturm and Drang and I rarely dig that.
The Last Detective was quite good but his personal troubles with the ex was the weakest part of the show. I like an interesting parade of suspects and characters being interviewed and/or assaulted with very little personal time out.

As a huge lover of Inspector Morse, I've never been able to get into A touch of Frost. I find it a bit clunky & the writing is no where near as good. I can see if you watch it regularly it might become a more comfortable watch. I have read a couple of the books too, but they feel so dated to me, with the casual sexism especially. But the writing it self I don't think compares with the likes of Colin Dexter, PD James, Reg Hill etc.
I do recommend Endeavor if you can see it - I think it is second to Morse over Lewis (some of the story lines in Lewis were just too absurd & so far from Colin Dexter's clever writing).

'Midsomer Murders', 'Cadfael', and the old '70's series 'Private Eye'; skip 'Foyle's War' unless you have a penchant for series where every single episode is about "German Spy Espionage" (I realize the series takes place during WWII but repetitive, identical plotlines get boring as hell).

There's no real chemistry in Frost. The stories are good, but a lot depends on whether you can identify with the self-conscious cuteness of the Frost character as played by David Jason. I found after a long while watching (and re-watching) them that the good episodes are the ones where the cute touches are played down and especially where there is some element of tragedy for Frost himself in his personal and/or professional life. In contrast, I've never much cared for Jason's comic characters, at least not since his early "Edgar Briggs" in The Top Secret Life of Edgar Briggs from the 1970s -- a series which Jason won't allow to be shown again reportedly because he was a little green as an actor, though much funnier than he's ever been since.

Glancing through the replies it's a very thoughtful, reasoned response. I'm a fan of all the shows referenced. Key difference with Frost is that David Jason is from the comic actor tradition. Comic elements are found in all the shows but is more pronounced in Frost. Frost is more a comic character despite his competent success 'nicking villains'. Let me recommend Vera and Last Detective as worthy genre entries.

If you are looking for an ensemble and connection between the main characters I would also recommend Foyle's war which isn't just Nazi-spy-of-the-week as another poster suggests, but crimes based on true happenings during the war. Also, Michael Kitchen is an incredible actor.

Another suggestion is New Tricks which has great ensemble acting by a group of veteran actors who play retired policemen solving cold cases.

Both of these series fall more into the "cozy" genre like Midsomer and even Lewis, rather than the gritty cynical world of Frost.
