I still can't stop but think how stretched out the Hobbit films were, for an otherwise short book. That's a sin that stains forever with me. The Lord of the Rings films, do have their own flaws, but they're fairly contained and can be debated as to whether they were good or not. I have so much trouble excusing anything with the Hobbit though.
And I hope we never, ever see anyone tackle The Silmarillion. Simply because, there will be so much improvised fluff in that would-be film, that it'd make the Hobbit films blush.
I was never a big tv watcher to begin with but after that whole fiasco I realized the whole thing is a scam designed to string you along for as long as possible. They start with one or two good seasons and then just wing it until it runs out of steam and don't give a shit about the story as long as they're making money. So disrespectful to the viewer's time and emotional investment. It violates a basic principle in storytelling: begin with the end in mind.
I quit watching all TV after that, with the exception of the Walking Dead (due to the gf's insistence) which only further cemented my convictions.
