Like the OP, I'm actually NOT happy with the cutscenes and cinematics in the game AT ALL. they are poorly crafted and poorly executed, and it has nothing much to do with the overall graphical quality. The writing is bad, the choreography is bad, and the execution is bad - even for the important supposedly major scenes.
Another thread by an individual with far more training in this particular area than I have made an excellent post and video (for those who would rather watch and listen for a couple of minutes, with visual examples, rather than read), and I'd very highly recommend that folks here take a moment to remind themselves of it:
