I never followed Midsummer murders, so I wouldn't know.
Personally I could swallow the main charachter change in Comissar Rex, but heck after a couple of season I wasn't a true follower/watcher of the series anymore.
My mother is, as my father often jokes about, is fond of those old series from around the '80s. Especially the A-team. The rest of the family has had it with most of those series, and it is her not so secret guilty pleasure. And ok, when being a teenager I have seen Santa Barbara, The Bold & the beautiful, Murder she wrote, Father Dowling, Comissar Rex etc. with her.
It was BTW only later that I discovered the A-team started with another 'Face'. In the pilot Face was played by Timothy P. Dunigan, who was later replaced by Dirk Benedict.
Talking of old shows, then I used to watch "Monk" and I felt pity for Monk's phobias and anxieties. Now 10 years have passed and a lot of people carry with them a supply of sanitary wipes [me included] and use them often, now even more so
