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.
