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 haven't read the books, but have heard recommendations for the show. I tried to watch it, but had to turn it off after the first three episodes. The visuals were great, but I found the writing and dialogue to be really bad. So many heavy handed references to that girl being smart. Counting prime numbers for fun while swimming or something up to an impossible number, etc. There were other things but that's what I remember for some reason.
Usually when I notice something like that it persists, so I stopped watching. Did the dialogue bother you and did it get better, or is this just a subjective a taste thing?
