Must See: Third Rock From The Sun
Must-see TV shows are futuristic classics that shouldn't be missed. Of course, not every must-see is perfect. That's why we've rated them 1-5 on the patented "crunchy goodness" scale.

Title: Third Rock From The Sun
Date: 1996-2001

Vitals: Four aliens come to Earth and take human form to study us. Along the way, they fall in love and become obsessed with our zany culture. And sit on the roof a lot.

Famous names: John Lithgow, Kristen Johnson, French Stewart, Joseph Gordon-Levitt, Jane Curtin, Bonnie Turner, Terry Turner

Crunchy goodness: 4

Elevator pitch: It's like Mork times four — and one of them is a badass chick!

Life lesson: It's frighteningly easy for an alien like Dick (Lithgow) to fit in in academia.

Stunt casting: Curtin as Dick's colleague and eventual love interest. As the main non-alien character on the show, she brings a lot of comic timing and, weirdly, great dignity.
