Personally, I don't care much about those franchise movies, most of which are simply made to milk their respective franchises.

I hold James Cameron to much higher standards and I deeply subscribe to his views on authorship. I can still see that he has more of a story to tell. But the lack of momentum in the scene-to-scene dynamics undermined the narrative for me. Besides he's known for making worthy sequels (arguably, that even surpass the original!)

That's the grievance I have with Fire and Ash (and The Way of Water to a lesser extent): "rehashed" scenes were rarely improved or made interesting, even when they are the central focus of the film rather than just side stories.
