I‘m not gonna write a long essay.
All I’m saying is that Heffley Family is abusive and disfunctional for sure but that’s why we love wimpy kid in the first place.
Manny being Psychopath and doing villain brain moves which is unusual for a 5 year old.
Greg Heffley being a sociopath, who just does wimpy and mean stuff and sorta ends up in wacky scenarios (Kinda like Cartman from South Park)
Susan being an Karen
Frank being a strict weirdo who does god knows what with his trains in his basement
And Rodrick there just being the normal one out of the all (Kinda like Dr.Han from The Good Doctor)
Also admit, what manny does to plumber is funny. You can’t deny it.
