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 think Bungie fumbled a bit but overall did a good job telling the story of Master Chief. Halo 3 really felt like it was intended to be his end because MC was right back where he started - A super weapon kept in cryo, only this time drifting indefinitely into space with very little chance of ever being found.
Then Bungie did Halo: Reach as a follow up and showed you could have a good Halo game without MC as the protagonist, telling a new(ish) story with new characters.
Then of course Microsoft ditched Bungie and kept the IP, now looking at now the vast amount of Halo novels and comics and other media, decided to dig up Master Chief again and shoehorn him into a bunch of other game plots.
I won't say Halo 4/5/Infinite are terrible or anything to that level but I don't think 343 nailed it.
Even more frustrating now that Microsoft seems keen to remaster the whole Halo Master Chief story arc (again).
