20th Century Fox Family Guy Season One Episodes 1-7 - Electronics | Color: Gold
Watching Season 1 now is a jarring experience. Before the cutaways became a crutch, before Stewie turned from a megalomaniac into a flamboyant domestic, the show was a low-fi, angry, and surprisingly clever satire of the All in the Family era. The seven episodes (including the unaired pilot) are slow-burn character studies disguised as cartoons.
