SpongeBob SquarePants is an American animated television series created by the late marine biologist and animator Stephen Hillenburg for Nickelodeon.

Why it's mixed

 * 1) People had mixed receptions on these seasons. For example either people think Season 4 or 5 will be the last good season and/or will be the first bad season in the show.

Season 9b-Present

 * 1) Awesome Animation.
 * 2) Really Great Choice of music.
 * 3) The characters have redeemed themselves from the dark ages (2008-2012)

Season 4-5, 9a

 * 1) It was the same era (Post-Movie to be exact) where it had a TV movie named "Atlantis SquarePantis" which is not well-recieved by viewers.

Season 9b-Present

 * 1) It has weaker writing compared to the first three seasons and even season four of the show.
