If you can get through the first episode and like it, you're probably good for the season. As characters are introduced, we are taken into a world where there's not much room for believability or a truly plausible mystery.
Instead, this show is more of the Matlock/Murder She Wrote/Charlie's Angels school, which is simple, easy, stagy, and at times making attempts to be mildly humorous. I appreciate the advanced age of the cast, because old people have adventures too, although one might speculate perhaps the star/creator/writer chose her cast in part because so many are obviously older than her.
One might wonder, though, why the characters of Judith and Jeremy, both played by actors in their seventies, are so broadly and loudly portrayed. Evidently the two actors are TV veterans, not the stage, and yet they play their parts like community theater actors trying to get noticed by someone in the back row. They need to rein it in a little, imo.
My wife and I are both fans of British crime dramas such as Line of Duty, Dalgliesh and Manhunt, maybe some Grantchester thrown in as well, but we found this more frivolous variety of "mystery" unwatchable. It is to mysteries what Doc Martin is to medical shows, except that Doc Martin is quite entertaining, well written and very well acted.
