The show is extremely immoral, no consistency (which is also necessary for morals to work in a show), and shows immoral characters positively (that’s why people love Barney for example even though the guy should at least be in jail).

So while The Good Place is a working recommendation that someone else made (that still has a LOT of flaws but at least try to add some concepts of morality, philosophy, etc), HIMYM does the opposite of that by refusing to ever think about moral issues of what is going on.

So my point is, if HIMYM seemed like a moral-teaching show to you, most shows will be, but that’s not positive.

If you want shows that try to talk about morals, you can look at the (old) star trek. I would say the least bad for that would be TNG and VOY, but they still need to be taken with a grain of salt.

Doctor Who also can work, if you want something a bit more on the horror/thriller/mystery side, but also needs a grain of salt and some critical thinking.

Science fiction in general tries to talk about philosophical subjects, while being entertaining, but a lot of what is seen as science fiction is just action movies in space.
