That '70s Show is a popular sitcom that aired from 1998 to 2006, capturing the spirit of the 1970s. The show follows the lives of six teenagers and has recently been renewed for a sequel series, That '90s Show. While the show remained of good quality throughout its eight seasons, the final season did show some deterioration with the absence of fan-favorite characters. Season 7 felt like the beginning of the end, lacking originality in its storylines.

Season 6 had some great storylines but suffered from forced relationship drama. Season 4 saw Donna and Eric apart, allowing other characters to shine but feeling unnatural. Season 3 found the show's success formula and had strong storylines. Season 2 was ridiculous in a good way, offering laughs and exploration. Season 1 introduced the characters and relationships that made the show popular. Season 5 was entertaining and surprising, with unexpected twists.
