If you haven't already seen them, I highly recommend The Wonder Years
and Family Ties
, both available on Netflix. I'd seen bits and pieces of these shows throughout the years, but now I've been sitting down and watching them in full, and they are really great. The Wonder Years is my top choice. It has a lot of variety to it; certain episodes are very poignant, serious, and even heartbreaking. And then the very next episode will be really hilarious and light-hearted. It's really a classic show that I love spending my time on.
Another suggestion, also on Netflix and still airing new seasons, is Bones
. A really awesome show, and not as formulaic as it may sometimes appear!
