SpongeBob SquarePants (seasons 6b and 7)

SpongeBob SquarePants is the main character from the American children's animated television series of the same name.

Why He Sucked (Seasons 6-8 only)

 * 1) He was an annoying, idiotic crybaby.
 * 2) He was HEAVILY flanderized and became EXTREMELY out-of-character to his original character in the first three seasons (though, it varied whether he was in character or not in the fourth or fifth seasons).
 * 3) Sometimes he could be a jerk, doing things such as digging a whole in the road to make Squidward wreck his bike, laughing and making a joke about Mrs. Puff getting injured, kidnapping the townspeople by trapping them in bubbles and bringing them to his house (it makes sense in context), apparently lacking empathy, causing boat wrecks (albeit unintentionally) without feeling remorse for it, and scolding Gary for things he clearly didn't do and not thanking him when he saves his life (in the same episode, by the way; and not to mention, he also stole a pet from a store in the same episode).
 * 4) He almost never acted his age.
 * 5) He turned mean-spirited, which is a character downgrade that was unexpected, especially for Spongebob. For example, he repeatedly told Gary off for being mean to the new pet, when the new pet was torturing Gary.
 * 6) His cartoon gags just turned irritating and unintelligent.

Redeeming Qualities

 * 1) His behavior was alright in some episodes, such as Sand Castles in the Sand (although, he may have been a little flanderized and out-of-character in that).
 * 2) He got improved past Season 8.
