Hubris the size and shape of someone named Jackson? The BBC for making an animated Hobbit? No written tome is ever going to come out unscathed in a TV/film adaptation. Have you seen the Amazon Jack Ryan series, the Without Remorse movie?

Hubris, arragance, etc. You're coming back to words that mean the same thing. Just because it's a work you personally are not familiar does not make it more/less egregious that someone has taken the material in their own direction from the original. It's just that you have a personal connection to the orginal and may or may not like the reworked version.
