I just heard the Unit is getting cancelled, whic I love.
As for back in the day, Misfits of Science, Whizzkids (which would be better if made today) Young Indiana Jones & Tales of the Gold Monkey.
I don't know if anyone's seen this but there was a teen-drama called "Life As We Know It" and after one season it was cancelled, because parents complained it was too sexually oriented. As if that's not all 17 year old guys think about. Anyways that's the only one i can think of right now.
