There is also a show called Dragon's Den. It's the same thing as Shark Tank, but a Canadian version I think. It even has some of the same people in it, like Kevin and Rob (I think his name is).
Lie to me is also good, but since it's fiction there are some issues with it. One example in, if I recall correctly, season one has Dr. Lightman saying that the person he's questioning is showing one feeling but Dr. Ekman (on whom the show is very loosely based) notes that it's more of a confused shock than what the show said. It's still good, mind you, as it tries to follow the whole micro expression thing, just know that actors don't always get it right.
It's definitely entertaining, though, and does share some information on micro expressions, especially in the first season.
