Lisa Simpson (seasons 7-30)

Lisa Simpson is the oldest daughter in the Simpsons family; older than Maggie, but still younger than Bart. She unfortunately received a lot of flanderization, even during the golden age of the show.

Why She Sucked

 * 1) Lisa has gone all over the place and has flanderized a lot quicker compared to most other characters in The Simpsons, she originally started out as the smartest and "best-behaved" character just in contrast to Bart, but nowadays she is a complete know-it-all Mary Sue and a massive SJW.
 * 2) Much like Brian Griffin, she essentially became a political soapbox for the creators of the show. This is very noticeable in the 2007 movie where she nagged the town about the lake being polluted, and in "Lisa the Vegetarian", where she trashes her father's barbecue all because she is a vegetarian and doesn't like eating meat.
 * 3) Because of her Mary Sue personality, her intelligence was dialed straight up to 11 and seems to always outclass her peers very badly.
 * 4) She is a bigot. She has had some moments of being intolerant towards others opinions like how she calls Marge dumb for believing in angels, and she holds her vegetarian beliefs against anyone who is not a vegetarian (as mentioned earlier).
 * 5) Lisa became a hardcore activist and almost an extremist, her sardonic view became a Holier Than Thou superiority complex.
 * 6) Her nerdy interests became a patronizing enthusiasm for the most pretentious of vocations.
 * 7) Somehow, Lisa knows obscure facts that no kid her age, not even a smart one, would know or care about, such as when Texas was admitted to the Union, that Monaco has a prince, or what Occam's razor is, yet somehow she doesn't know where babies come from.
 * 8) In later seasons, Lisa eventually became the female version of Martin Prince due to her being portrayed as very uncool and she lost most of the friends she had in the earlier seasons.
 * 9) She is at her absolute worst in episodes like "Bart vs. Itchy & Scratchy" and "On a Clear Day I Can't See My Sister".
 * 10) *In "Bart vs. Itchy & Scratchy", she publicly humiliates Bart after he laughs on a gag of a Itchy & Scratchy girl reboot by publishing the stream that Bart was in onto the internet, causing Bart to get beaten up at school.
 * 11) *"On a Clear Day I Can't See My Sister" caused Lisa's flanderization to kick in harder and it ultimately completely ruined her character all together, due to her acting extremely unlikeable towards Bart by getting a restraining order towards him.
 * 12) In almost every single episode that involves her being in a conflict with something, she's always portrayed like she's in the right of the conflict, always comes out on top, and they are always at a desperate attempt to make you root for Lisa. Like in any episode where Bart is superior to Lisa at something, and the episode tries to paint Lisa as sympathetic despite that she's just being jealous of Bart, which is a petty reason to make her sympathetic.
 * 13) She is shown to be willing to abandon her family in pursuit of glory.
 * 14) * In "Elementary School Musical", she ran away to pursue a career in performing arts.
 * 15) * In "MyPods and Boomsticks", she goes to the Mapple HQ without telling her family or ask them about the bill problem from it.
 * 16) * In "Lost Verizon" (The episode that started this trend), she then waste all her family time to go the Peru despite the gps chip is part of the bird and they are seaching for Bart.
 * 17) She's always butting into people's business and trying to force her opinions onto people when they don't ask for them or want them, basically making her as Ned Flanders calls her "Springfield's answer to a question no one asked".
 * 18) Even when she isn't being unlikeable or political, she can be treated like a butt-monkey at times as well, such as in "My Sister, My Sitter", "Lisa Goes Gaga" and "Bye Bye Nerdie".
 * 19) She is extremely hypocritical, or self-serving in a lot of her causes. One infamous case being her motives for joining the school football team, becoming upset when there were already four girls on the team.
 * 20) "You shouldn't be part of a protest if you don't care about the cause." 

Redeeming Qualities

 * 1) Lisa is still a far more likable and funny character due to the fact that she is still a Hollywood Walk of Fame character like Ms. Piggy, even in the old and new seasons.
 * 2) She can be likeable in a few episodes like "Mother and Child Reunion", "Lisa's Date with Density", "HOMЯ", "Lisa's Sax", "My Sister, My Sitter" (despite being treated like a butt-monkey), "The Way of the Dog", etc.
 * 3) She was way more likable before season 7.
 * 4) Similar to Homer and Bart, there are still episodes where she is at her best.
 * 5) In "The Man Who Grew Too Much", it's shown that she's for GMO, something that SJWs would attack, meaning that she's not always alt-left and she can give new science a chance, despite her flanderization.
 * 6) She started to improve in season 31, since she started to be not as political.
 * 7) * She even mocked SJWs in the season 32 episode "Wad Goals".

Reception

 * Lisa mainly received mixed-to-negative by fans of The Simpsons, mainly due to her becoming a political soapbox for the creators. Some fans even go as far to say that she is the worst character in the entire series.
