MacGyver ('85-'92) became one of my favourite shows after going through the box set a few years back. I didn't like it as a kid, probably because it wasn't the A-Team (think it took over the slot on ITV). Quantum Leap ('89-'93) is generally a quality show too. I did like that back in the day due to learning about history and watching it years later it still holds up.
What innocent times we used to live in, where simple stories about a good man* driven to help people and fix problems were considered entertainment.
* The fact it was almost always a white man, or group of men, is something I'm glad we've improved upon though.
