Bart Simpson (seasons 16-30)

""Bart? Are you Bart Simpson? You stink like a Dutchman's throw-up! Liking you was the biggest error of my life!""

- People when they saw how badly flanderized Bart was in these seasons

Bartholomew JoJo Simpson, nicknamed Bart is the deuteragonist of the long-running American sitcom, The Simpsons. He is the mischievous and rebellious eldest child of Homer and Marge Simpson, and the older brother of Lisa and Maggie. Sadly, he got flanderized during seasons 16-30.

"Ay, Caramba!" Qualities

 * 1) He has gotten flanderized, losing a lot of the charm and likability he had in the first ten seasons, though it varies whether he's in character or not in Seasons 11-15. During these seasons, he’s gone from a mischievous and rebellious prankster with a heart of gold into a malicious sociopath who takes delight in causing trouble for others. Here are some examples:
 * 2) *He terrorizes Seymour Skinner and Edna Krabappel on many occasions. It’s true that he liked to mess with them in earlier seasons, but not to the extent in these seasons.
 * 3) *In "Please Homer, Don't Hammer 'Em", he blackmails Principal Skinner by threating to give him peanuts, even though he's allergic to them.
 * 4) *He intentionally exposed himself naked to the public in The Simpsons Movie.
 * 5) *He is at his absolute worst in "Love is a Many Strangled Thing", as he acts like a complete sociopath to Homer and doesn't even try to save him from being hung.
 * 6) He can be extremely selfish, similarly to Mr. Krabs.
 * 7) He can also be careless. For example, in "The Heartbroke Kid", he binges on vending machine food without realizing that it's bad for your health.
 * 8) Sometimes his parents don't properly discipline him when he acts up.
 * 9) When isn't acting unlikable, he can be treated like a massive butt-monkey at times, such as in "On a Clear Day I Can't See My Sister", "The Boys of Bummer", "Bart vs. Itchy & Scratchy" and most of Season 30.

Good Qualities

 * 1) He was a much better character in Seasons 1-15 and has redeemed himself since Season 31.
 * 2) *Though depending on your view, he, along with his dad, can still be likable and have his original personality in some episodes.
 * 3) He does get his comeuppances after his antics go way too far, so at least he cannot be considered a Karma Houdini.
 * 4) His catchphrases, including "Don't have a cow man!" and "Eat my shorts!" are still funny and memorable.
 * 5) Nancy Cartwright still does a good job voicing him.
 * 6) There are times when we can sympathize with him. A nice example being in "The Boys Of Bummer", given that he was bullied so much that he even attempted to commit suicide in that episode.
