I don't know if it's just a nostalgic thing, but I love me some 90s TV. I will do a top 10 list later on but for today I just wanted to quickly recommend one of my favourites.
Frasier. Frasier is a show I have watched in its entity at least half a dozen times. Really it has become a kind of comfort watch for my boyfriend and me, something we put on when we can't decide what to watch next but it is honestly just such a fun show.
Frasier began as a spin off from the show, Cheers, another series I have seen all of but wouldn't overly recommend as I don't feel it aged particularly well.
The title character is a radio psychiatrist, living in Seattle with his father but for me the reason to watch the show is Frasier's brother Niles and his father's physical therapist, Daphne.
If you've never given it a chance or only watched an episode here or there, I suggest starting from the beginning and seeing the story play out. It's far from perfect but it sure is enjoyable.
