This sitcom is about a group of aliens who land on earth. They settle in suburban Ohio - where they live in an attic apartment, pretending to be a human family. John Lithgow is excellent as the protagonist, the group's high commander, whose human character is Dick Solomon, the father of the family and a physics professor at a university.

This show gives hope to would be sitcom writers everywhere as it's a prime example of how you can make one joke (aliens living on Earth) last for 6 series.It's a well acted sitcom, I can't argue about that, but by the end it had run it's course, notably by the fact that the boys had grown up. John Lithgow holds it all together though, and is an underrated actor in my option.It's never had the longevity of other sitcoms of its time either, and that's a shame, because there's a lot to like.For me though it's one joke spread out for a rather long time.

The premise of 3rd rock from the sun was a group of aliens observing earth behaviour and they do this by inhibiting human form and pretending to be a family for their mission and living in everyday America.John Lithgow is the father figure and is a professor, Kirsten Johnson has to deal with a female body and a teenage Joseph Gordon Levitt has to deal with the body of a kid. French Stewart gets to do some physical comedy and the comedy is a mixture of intellectual and physical comedy and also acted as a satire. The series was bouncy and spritely as its starting titles of planets zipping about.The first three seasons were rather sharp and consistently funny. John Lithgow led the cast in a series that reflected the mid 1990s and away from a Reagan/Bush USA to a Clinton era America.

3rd Rock From the Sun always had something different about it. Something new. That no other show had. I could never really figure it out.Until the series finale, at the end, where their holding each other before they leave for the Home Planet, like a family.People talked a lot about how funny, and original the show is. But it's much more than that.For 6 years, we watched aliens disguised as humans try to fit into society as a fake family. But what they didn't realize, was that they were a real family.The show follows four aliens, Dick (Lithgow), Tommy (Gordon-Levitt), Harry (Stewart), and Sally (Johnston) on a mission to discover their customs on Earth. Dick is the High Commander of the mission. Tommy is the Information Officer of the mission. Sally is the Security Officer. And Harry.....has a connection thing in his head so the Big Giant Head (their leader) can send messages to them.The show contains great acting by John Lithgow, French Stewart, Joseph Gordon-Levitt, Kristen Johnston as the alien family. Jane Curtin, Wayne Knight, Elmarie Wendel, Simbi Khali were great supporting actors, too.The only thing that I can really find wrong with the show is that it did take a downward slope in the sixth season. It wasn't as funny, and some of the jokes fell flat, but it was just as entertaining and enjoyable as ever. And the series finale was the best 3rd Rock episode since the fourth season.If you want to see a show with great acting, writing, an original story with creative plots for each episode. Then watch this show before all others.
