Leni Loud (seasons 5-present)

Leni Loud is one of the main characters in 1st-4th season and the deuteragonist in 5th-present season of the Nickelodeon series The Loud House. While she was tolerable for the most part in seasons 1-4, she has received flanderization in	Season 5.

Bad Qualities

 * 1) Like Lincoln Loud, she became flanderized. But unlike him, she went from a compassionate teen, to an even dumber person. Now granted, Leni was the airhead of the show, but she wasn't that stupid in the earlier seasons, not even to the point of being very dumb to the point it's not even funny anymore.
 * 2) In "Schooled!", she acts like she lost all of her IQ, as she confused High School with Preschool. Which is considered not just the stupidest moment she has done in Season 5, but in the entire series. It does not help this would later be put back in "Appetite for Destruction" as a callback, as if the writers didn't learn their lesson from "Schooled!" and the fans.
 * 3) She has became even more irresponsible in this season as well.
 * 4) She mostly has clumsy/accident-prone moments and a true Butt-Monkey in the series due to her ditziness.
 * 5) In "Electshunned", she tried to run for mayor of Royal Woods despite the fact she's a minor and and not even a politician. Thankfully, she quit in the end and was nice.
 * 6) *She is at her worst in the episode "Grub Snub" where she makes such a big deal of Lincoln and his friends hanging out at Gus' Games and Grub and then she tries to get Lincoln to leave Gus' Games and Grub. In fact, during the final round of their challenge, all of them start fighting and destroying all the arcade games which causes everyone else to run away from Gus' Games and Grub. They even injured the owner, Gus Gamesngrub and somehow are allowed back in the arcade instead of being banned.
 * 7) What makes it worse is that in Season 4, she actually started to get a little smarter in that season, which was pretty good character development. But in this season, it is all thrown away.
 * 8) Her voice in the live-action Christmas movie, Dora Dolphin, sounds nothing like her original actress. In the upcoming series, there is a possibility that she will be replaced.

Good Qualities

 * 1) She was better in Seasons 1-4.
 * 2) She sometimes has her original personality, such as in "The Boss Maybe" and the end of "Electshunned".
 * 3) At least she still cares for her friends and family, especially Lincoln.
 * 4) Like modern Lincoln Loud, she still has her fair share of funny moments.
 * 5) Depending on your view, she improved a bit in Season 6, as she isn't as dumb there, similar to Lincoln Loud in Season 5.

Trivia

 * In Schooled!, she starts 12th grade.
 * Starting in season 5, she is now the deuteragonist of the series (replacement for Lori) due to Lori is now moving out from Royal Woods to attend Fairway University with her friends.
