As Bob mentioned in his DVD post this week, The Mary Tyler Moore Show: The Complete Fifth Season was released in a 3-disc set on Tuesday. I have fond memories of watching this show as a kid, and the clips after the jump confirm once again that it featured one of the best casts in TV history.

Not only was each actor perfect for their role, but their timing and delivery of lines was second to none. I also love all of the 1970s-era props, clothes and decor, because of course, the show was made in the 1970s.

In AOL TV's continuing countdown of the best TV shows of each decade, we're back to break down the 1970s, a decade when the cop dramas were less gritty, the families were close-knit and the sitcoms were sprinkled with serious social commentary.

Our list of the best shows of the '70s features many of the best shows of all time (here's looking at you, 'Mary Tyler Moore Show,' 'M*A*S*H' and 'Taxi'). Take a gander and let us know if you agree.

It's not easy winnowing more than 50 years of small-screen gems into a list of 50.

But AOL TV's picks of the top TV dramas include the most brilliant doctors and lawyers, the angst-iest teens, sci-fi series that transcend their genre molds, family dramas that both warm and break your heart, terrorist- and mobster-fighting heroes ... and a show that combined the best of family and gangster drama into one unforgettable series.
