Oh boy, more unnecessary Louie hate. Not that people have to like his character, I can get why they don't. But saying he "never had much of a heroic moment" is Mabel Pines level of ignorance. Louie has done a lot of heroic things, arguably some of the best in the show. And like, if you are going to go at Louie's throat for being mischievous, then by proxy you'd have to go at almost every other character in this show as they all have a bit of mischief to them.
Ultimately, you can have whatever opinion you want on Louie, but don't say stuff like "he has never performed a heroic act" cause he has. He very much has.
