TBH if the same story had been told at the same pace as the first few seasons (and had actual consequences for dumb decisions), it could have worked.

I forced myself to rewatch it recently since someone at home wanted to and it certainly was a let down, but mostly because of how it was clearly rushed and turned into a Hollywood blockbuster. E.g. people charging into an army and surviving every time, which I know he was strongly against.

It felt like the broader strokes were there, but the show runners had no imagination of their own to make it flow properly, and might have kept more characters alive than needed to avoid upsetting fans instead of telling the story as it was meant to be told.
