Nickelodeon (2009-present)

NOTE: This is the first article! Nickelodeon is a kids TV channel that has ran for at least 40 years, making it the longest running Kids TV channel ever. Sadly, it suffered a dark age beginning with SpongeBob SquarePants' sixth season.

Bad Qualities

 * 1) It ruined SpongeBob SquarePants, as mentioned before, with the sixth season, and would not improve until the ninth season. However, some say that it was the fourth or fifth season that began the dark age of SpongeBob, and even that it started to improve in the eigth season and it was the seventh season that concluded the dark age. People even say that Season 9a was bad, and Season 9b was after the dark age.
 * 2) Fanboy and ChumChum is the worst Nickelodeon show by review.
 * 3) Henry Danger is unlikable, as it's like a 13-year old wrote this.
 * 4) Sam & Cat is an awful spin-off to iCarly.
 * 5) Due to running for at least 40 years, previously mentioned, Nickelodeon will often jump the shark, both in the dark age and out of the dark age.
 * 6) The Fairly OddParents was also bad too, though the sixth season was when it jumped the shark, the ninth and tenth season KILLED the show.
 * 7) * Season 9 introduced Sparky, a completely USELESS character. He's basically a hard copy of Dukey.
 * 8) * Season 10 was even worse. Sparky received so much hate that he was removed completely with no explanation. His replacement was Chloe Carmichael, an even worse character. She's a flawless Mary Sue, and Timmy has to share with her. And this season was after the dark age.

Good Qualities

 * 1) The Loud House thankfully concluded the dark age of Nickelodeon
 * 2) SpongeBob SquarePants started to improve after Season 9.
 * 3) Fanboy and ChumChum also started to improve after Season 2.
 * 4) There were some good shows in the dark age. Examples are "iCarly, and Victorious."
