1st I must congratulate you on your excellent English.
And it is interesting that by divesting your interest in the characters and by lowering your expectations you derived more benefit from re-watching the movie.
I actually saw the movie last night too-in Italian.
I would wager also that the Italian dub actually sounds more organic with regards to the dialogue(relative to it's english equivalent).
I was watching it in 4K-it looks amazing but you can also see some of the lip synch issues in both English and Italian-like when Ani chants "yes!" after he has won the pod race.
I would say the biggest discrepancy between this movie and any of the OT films is the fact we already knew what was going to happen -we just did not know how it would happen-this fact allied to the expectations that were affiliated with our perception of how certain characters(or groups like the Jedi council) would behave or be(especially those from the original trilogy) also handicapped the experience of watching this flick.
Compared to other summer block buster fares I can't think of a series where the main protagonist ,Anakin , goes from being good to bad completely without any sense of a reprieve-this in my opinion makes it unique-irrespective of how well this conversion from good to bad is executed.
It did not happen in Harry Potter , The Matrix, Lord Of The Rings, Transformers ,any of the super-hero movies(ok Raimi's Spidey 3 for about 20 mins!),Avatar-(never seen Twilight so don't know) or the Hunger Games-my apologies if I have missed something.
So the trick is to take a some-one (young or old) who does not have a clue about anything star wars and expose them in episode chronology- just to see how shocking(or not) this conversion from good to bad is.
