i watched this show in the 80's , it was fun then but it is not fun anymore.Family Ties was a more quiet and intellectual series about Baby Boomers who had older Gen Xer kids. The show used intelligent witty humour instead of sight gags and slapstick comedy.
On my list comes second after the Cosby show.
I loved it when Alex told his dad to join the eighties, and then thought about it more and said more emphatically, "Join the seventies!"
The show had many serious moments as well though, dealing with death and terminal diseases amongst others. In fact, the episode with him reminiscing about a friend who had just died (I forget the title) won awards for best TV show in the year it which it was broadcast.
