Spongebob is Nickelodeon's Mickey Mouse! Literally!
The 1st Season is legendary (with beautiful traditional animation),
The 2nd, 3rd, and 4th Seasons are amazing (because Hillenburg, but why flash computer animation, ew),
Then Hillenburg knew the show went on long enough so he made a grand finale as a movie, The Spongebob Movie! And it would have been the ultimate finale (the movie is a legendary classic).
But the audiences said NO and forced the show to go on. Tibbet was good and decided to stay to direct the show. But as the show went on TOO LONG, their was a decrease in quality.
The 5th Season started the downfall, but was fine,
The 6th Season WAS the downfall, and should be erased from existence,
The 7th and 8th Seasons followed the rules from the 6th Season,
The 9th and 10th were starting a mini-rise with much of the old producers coming back, wanting to restore the classiness of the first seasons,
Then Hillenburg was like "I'm back" and directed (The Spongbob Movie 2) Sponge Out Of Water which was probably even better then the first seasons! Hillenburg was serious and made this masterpiece!
The 11th season was confident in keeping the show alive after the movie,
But then, out of nowhere, the legend, Hillenburg, died. Now SPONGEBOB NEEDS TO END!
The 12th and 13th Seasons are cashgrabs/showrunners of tiny hope,
The Spongebob Movie 3 is also a cashgrab or movierunner,
That is The Legend of Spongebob
(1999-PLEASE END AFTER THIRD MOVIE)
