I recall watching Hello Tomorrow which was a quirky atompunk themed comedy from Apple. It wasn’t perfect, it wasn’t especially funny - but it had a charismatic affable liar as a lead that you found sympathetic despite his sleaze, and gave huge pre-war Fallout vibes. Apple silently cancelled it some time ago.
I would also argue Peacock’s attempt at Brave New World. Reimagined for the modern era (because really it had to be) and probably took more from Westworld than it did Brave New World, but it was doomed by being a Peacock original.
Halo has got to be a contender based on how little it actually accomplished across the two seasons before it was cancelled. All we got in the end was a very poorly written introduction to a story, though I’m still not actually sure what the story was going to be about because it basically stopped before it even started.
