I haven't seen anyone say galavant, that's a shame, somehow it got 2 seasons, and it's brilliant the whole way through. If princess Bride had more back story arcs, fewer restrictions on how over the top they could make their characters, and was a musical, you'd have galavant.

Going for the more obscure: Bajillion Dollar Properties. Originally made for a dead streaming service, now exists on PlutoTV for free (and can be purchased through Apple et al). It's a satire of real estate reality shows with phenomenal guest stars throughout. Main cast includes a few folks before they got their bigger roles (like Tawny Newsome, Drew Tarver, and Eugene Cordero) but also includes the GOAT, Paul F. Tompkins.

Very related, I would also suggest the Comedy Bang! Bang! TV show that ran for 5 seasons on IFC. It's a treasure trove of comedic goodness, lots of great guests, and who doesn't love Reggie Watts, Kid Cudi, then Weird Al as the band leaders??

Joe Pera Talks To You

'Ghosts' on CBS/Paramount+ is sweet, funny, lighthearted for the subject matter, and overall very enjoyable. I don't think it will win any awards, but its a great alternative to all the dark and cynical stuff out there!

It's Always Sunny?

On the surface, it contains terrible people doing terrible things, but it's both comedic and condemns those terrible things

Parks and Recreation. So funny. If you like the office you’ll love it!

Pushing Daisies.

Recently I watched and enjoyed Parks and Recreation and One Day at a Time (netflix series). Light hearted engaging content. Another recommendation: Schitt's Creek.

Close Enough.

If you're a weeb there's an entire genre of this stuff: iyashi-kei ("soothing type/genre"). I've enjoyed a bunch of them, though some of them get pretty saccharine if that's a worry. There's a large overlap with "slice of life", and a lot of these are set in school for whatever reason - YMMV. I like Azumanga Daioh, though the anime adaptation is a little aged. Nichijou is adorable and leans more into absurdism if that's your thing. "Yotsuba&!" is freaking precious, but manga only - same guy as Azumanga Daioh.

For non-weeb stuff I'll mention Brooklyn Nine-Nine, also Parks and Recreation once it hits its stride.

Lots of good suggestions so far, but not seen The Great mentioned. Filthy AF and one of the few shows I laugh out loud to (well, more like cackle loudly). I'll also second the suggestion for Better Off Ted.

The Great North, if you want to watch a fun and wholesome cartoon.

It is cancelled now, but Last Man on Earth is such a great show.

It's only one season, but Wonderfalls. It's pure joy. And all the episodes are on Youtube.

I'd highly recommend Avenue 5.

Schmigadoon!

It's very light-hearted and campy. Well, at least the first season is.

The Last Man on Earth

Bee and puppycat

"Miracle Workers" hasn't been mentioned yet, it has a similar vibe, romantic comedy, some mild philosophy, very upbeat. Each season is a different storyline with (almost) the same cast, so if the first season doesn't grab you try the next. The creator had an earlier show "Man Seeking Woman" as well, that's fun too.

Doc Martin

Obscure show, but watch Traffic Light on prime.

Broad City is pretty light-hearted
