In my honest opinion, this movie is everything a Star Wars fan would want and more: a great storyline, expansions to the Jedi and sith lore, one final tussle with the big bad, an explanation as to who Snoke was and a fantastic score (also, quite frankly, this movie has the best space battle out of any other Star Wars movie in existence)
Not to be one of those guys...but people who disliked this movie were corrupted by anti-Star wars propaganda that came with TLJ. If I were you, don’t listen to what anybody tells you about this movie, and see it yourself. You won’t be disappointed.
