Family Guy (Season 1-6)

Family Guy is an American animated sitcom created by Seth MacFarlane for the Fox Broadcasting Company. It has aired from January 31, 1999 to November 9, 2003, and has aired again since May 1, 2005. This era of the show is widely regarded as one of the best animated shows in television history, despite a dip in quality afterwards.

Why These Seasons Rock

 * 1) Being a show that was created in 1999 like SpongeBob, it's currently one of the longest-running cartoons that's still putting out new episodes.
 * 2) Decent animation.
 * 3) Likable characters, especially Brian, Stewie, Cleveland, Joe and Peter.
 * 4) Covers topics that are usually shunned by the public.
 * 5) Amazing voice acting, especially Seth MacFarlane himself.
 * 6) Tries to see how much it can get away with its dark humor and delightfully controversial jokes.
 * 7) Brilliant and creative episodes, such as the "Road to..." series.
 * 8) Hilarious parodies such as The Passion of the Christ 2: Crucify This!.
 * 9) Great songs, such as "The Freakin' FCC" and "The Bird is the Word".
 * 10) Helped to prove that people can have different opinions about shows despite crude nature
 * 11) Considerably realistic character designs.
 * 12) Memorable gags, especially the Quagmire gags and Peter's violent rivalry with Ernie the Giant Chicken.
 * 13) Even Scrat appeared in "Sibling Rivalry" as a cutaway gag with Peter saying these funny quotes such as "NO, NO, BAD SQUIRREL, THOSE ARE MY NUTS, MY NUTS" and Scrat attacking Peter while saying "Oh no, my nuts, my nuts", which was very hilarious.
 * 14) Many famous celebrities are fans of the show, such as Rihanna, Brittney Spears, and Dwayne Johnson.
 * 15) Brilliant jokes, without having to rely on shock value
 * 16) The fact that it was saved by fans after being canceled means how much people love this cartoon.

Bad Qualities

 * 1) Mild overuse of violence, sex, abuse, and farting due to how vulgar the show is.
 * 2) Some of the voice acting is pretty annoying, like Alex Borstein as Lois Griffin in the later seasons.
 * 3) Extreme amounts of toilet humor especially on the new seasons.
 * 4) Went horribly downhill since the 7th season's 11th episode: Not All Dogs Go To Heaven.
 * 5) *Even before the show’s downfall, the good seasons had the occasional bad episode, like Fore, Father.
 * 6) At some points it can rip off elements from The Simpsons, though that show also occasionally takes elements back from this one.
