I really enjoy the myth-busting aspect of Mythbusters, but I'm also drawn to it because it's a generally feel-good show featuring people cooperating.

To that end I'm trying to put together a list of shows that feature this vibe, whether they're along similar lines or not. And they're not necessarily high quality shows; the vibe is the more important part.

Here are some examples:

Closest direct analog I can think of: https://www.youtube.com/watch?v=3g53LtTqlRU James May did a show where they built some random things. It's pretty funny and has a childlike imaginative quality to it (it may have been made for children). I'm not sure if it's the exact same show, but he also built a house entirely out of Lego.

Completely out there: Republic of Doyle, White Collar, Eureka, Resident Alien, possibly Northern Exposure though I haven't watched it in a while, The Good Place, Stargate, Star Trek (the differences between each series could be a whole post of its own so not getting into it...there's something for everyone), Veronica Mars, Burn Notice.

These are not even in the same realm as Mythbusters, but they all casts generally trying to get along and cooperate. Some of them have much less drama (Republic of Doyle) and some of them have more of it (Veronica Mars). Some of them are in between. Some of them have a sci-fi aspect that might appeal to Mythbuster fans.

Somewhere in between: Grand Designs (especially New Zealand), Outback Truckers, Great British Bake Off, Baking Impossible, Nailed It.

These aren't the same setup as Mythbusters at all, but still about making things or cooperating.

Any other suggestions?
