Ask Lemmy

Ted Lasso

Parks and Recreation!

Schitt's Creek

My Name Is Earl is my favorite go-to light-hearted and positive sitcom. Follows the story of a rather silly, ignorant redneck that begins to believe in karma, and so writes a list everyone he has ever wronged and goes about fixing it one by one.

It's pretty good.

Taskmaster

Would I Lie to You?

Avatar The Last Airbender

Loremen podcast

Edited to add:

One Punch Man first season is hilarious.

The trifecta of 2010s animation: Regular Show, Steven Universe, and Adventure Time. There's jokes and themes in these that are pretty adult, but the darker stuff is generally avoided.

1980s: Dogtanian and the 3 Muskehounds. Mysterious Cities of Gold. Best theme tunes ever, and very easy watching.

Psych

Bluey pretends to be for kids but it's surely for adults.

I highly recommend Bob's burgers!

Good Omens.

Star Trek: Lower Decks

Schitt's Creek (was already mentioned but is worth mentioning again

Brooklyn Nine-Nine

Superstore

Derry Girls

Wellmania (sadly Netflix did a Netflix and discontinued another great show after only one season)

Or just rewatch The Office or Parks & Recreation once again 😄

I love sitcoms but beneath their light exterior they always have a heart of darkness, or at least a trace of one. But given your OP, I figure you can handle a teensy bit of a shadow side. Here are some generally upbeat shows with lots of laughs.

Catastrophe- I think it strikes the right balance of optimism in the face of doubt. It's light but not saccharine. It's my favorite sitcom.

It Crowd

Black Books

30 Rock

Black-ish

Adventure Time

Mentioned in lots of other replies:

Parks and Rec

New Girl (extremely underrated)

Unbreakable Kimmy Schmidt

Brooklyn 99

Taskmaster

WILTY

Community! If you like The Good Place you'll love it. It's my favorite show of all time

Our Flag Means Death is upbeat in the first season. The second is more dramatic, but also fucking phenomenal. A romantic adventure comedy becomes a romantic adventure dramedy.

Bob's Burgers.

Ted Lasso for the win

Detectorists

Here's a weird suggestion, watch all Mr. Bean shows. It's like one season and few episodes.

Scrubs

New Girl

Letterkenny!

I love "the good place". It's light comedy, it actually makes you think a little, it's a lot of feel good and it's one of those shows where you can see that everyone is having a blast making it.

Edit: I should finish reading the post before commenting, lol.

Star Trek the next generation

Brooklyn nine nine

One piece

If you love "the good place", then I can only recommend "parks and recreation". That is my all-time favorite show

Also recently I have started watching "Chuck". It's a action/comedy/spy series, there is ofcource action, guns and bombs. But Iam laughing so much each episode, I find myself rewatching some scenes.

Dirk Gently's Holistic Detective Agency

Letterkenny and Shirley if not Archer. Trailer Park boys

Agree about Parks & Rec and Black Books

Adding Boston Legal

Unbreakable Kimmy Schmidt

Happy Endings

Cougar Town

Community

Derry Girls

Parks and Rec

Ted Lasso, can't recommend it enough.

Kim's Convenience on Netflix.

British panel (game) shows like Would I Lie to You and 8 out or 10 Cats Does Countdown. The game element is just an excuse for funny, interesting people to crack jokes and have a good time.

The Venture Brothers is hilarious.

Pushing Daisies. If you like death mixed with comic book sweetness

Joe Pera Talks To You

Not adult, but The Owl House was a surprisingly good one. One of those multi-audience shows. Makes me think a lot of about the type of parent I want to be someday!

I don't think there is a more light-hearted show than Detectorists

How to with John Wilson, 30 Rock, Malcolm in the Middle, The Office, Nathan for You, Parks and Rec, Joe Pera Talks to You, Ted Lasso, Baskets (LOVE it, but can be a little sad and heartbreaking in addition to being hilarious and sweet)

Close Enough is a really great animated tv show by the creator of Regular Show. It's basically almost the same, but for adults.

Also, Workaholics

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

Letterkenny

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.

Schitt’s Creek and Letterkenny deserve some spots here
