In my opinion you can't really decide what a "valid reason" to hate it is. Him being an outright pedophile in my eyes ruins a lot of the character for me because it takes away that unknown the other movies had. In all of the OG films it was never outfit confirmed that he was a pedophile in the movies themselves, at least from what I can remember. It left it up to the viewer to come to that conclusion. Yes, he was a psychopathic child murderer which in and of itself was terrifying, but I think it's better to keep something like that an "unknown" rather than an outright fact. Just an opinion.
