I absolutely loved mythbusters, but honestly I think it ran it's course. They were kind of running out of things to test towards the end.
Also search for Streamlined Mythbusters - they're fan-edits that remove fluff (lots of fluff in the later seasons) and rearranges the shows so each myth is played straight through before going to the next myth in the episode; instead of showing pieces of 3 different myths at a time bouncing between them.
I feel like there were tons of movie related options had they gone back that direction. Easily a whole season's worth of action hero stunts they could break down.
Just one episode could be on Commando. Schwarzenegger ripping the seat out of a car, or killing a guy with a thrown saw blade, or impaling another guy with a thrown pipe. Would be interesting to have seen them figure out the actual force requirements.
Or carrying a tree on his shoulder. Arnold had to bust that one himself; the filmmakers thought that he could do it for real but Schwarzenegger insisted that he wasn't that strong and had them make a prop for him instead.
They could do years on Sci Fi tech, bringing down to what’s real, what’s possible. Didn’t they do a light saber at one point?
I’m watching the series Salvation and it is full of “advanced tech” that resembles reality somewhat. Imagine Mythbusters building the biggest rail gun they can, demonstrating both its potential and how it fails, and maybe even do a tour of military rail gun prototypes, then concluding with how much more the one in the show would have to be, and all the places it just wouldn’t work
A different but similar type show could be researching sci fi shows and showing how we can already do some of the things in a show and then show how it would look with current tech. And then if we already have or could build a way better thing with stuff we have today
The white rabbit project was a good show. Though it was a bit bitter sweet because I was watching it in 2020 and hadn't finished when Grant died. I wonder what kind of experiments he got up to in the afterlife.
They also missed a chance to educate the public about real science that uses blinded measurements and statistical analysis. Those tools aren't always necessary, but they are incredibly powerful to answer questions where qualitative testing can't.
