Hmmmm, could be I do have an outdated version, though I obtained it the day the final update turned green… The part I’m referring to is the part right after Bilbo puts on the ring to escape the fighting in Dale transitioning to Thranduil and Dain fighting orcs upon their respective mounts.
Also, I’m not ruling out the possibility that some of these transitions I am only finding abrupt because I have watched the originals.
EDIT: And yes, there was one other scene in the battle where I was going to make a similar complaint about the battle noise, but then I heard the music swell and let it go.
