The premise: In order to mask themselves as the average middle class white family, a group of aliens hides out in Ohio. Not a bad way to blend into white America at all. Each member of this masquerading family had a specific role, but Tommy (Joseph Gordon-Levitt) got the short end of the stick when he ended up with the body of a teenager. All four of the aliens are expected to report to their superior, the Big Giant Head, hilariously portrayed by Captain James T. Kirk himself, William Shatner.
Most of the show's early humor was derived from the aliens' struggles to blend into Middle America based on the bodies they'd been given. John Lithgow and Kristen Johnson towered over everyone, French Stewart squinted his way through the entire series and, in a nod to 10 Things I Hate About You (a wonderfully Caucasian teen classic), Joseph Gordon-Levitt's Tommy hooked up with Larisa Oleynik (aka Alex Mack,).
It's interesting that a team of aliens (or better yet, NBC) decided that pretending to be a strange white family was the best way to seem perfectly "human."
