There's a lot to be said about being fans of things as children and wanting those childish things to grow up alongside you, even though that was never the point of those things or their creators.
We live in an odd world where we have R-rated or "mature" adaptations of Scooby-Doo.
Of Archie.
Of Power Rangers.
And countless, colorful superheroes. We have an R-rated movie of Batman and Superman together. We have an R-rated Wonder Woman movie.
Peter Jackson's third Hobbit movie's extended cut is R-rated, despite being an adaptation of a CHILDREN'S book.
We want to enjoy the things we enjoyed as children, but we're embarrassed that those things are still childish. So we try and age them up. Adapt them to "mature" sensibilities. Sometimes that can actually work, but I think it's important to try and preserve the spirit of those things and what their creator's intended.
I probably never needed to see the plucky sidekicks from Superfriends torn to shreds by their adorable pet.
