Rogue One remains my favorite Disney SW film and the one I rewatch the most, but I agree it’s certainly overrated to some extent. Objectively it wouldn’t say it’s the absolute best of the modern films, much less the greatest thing to come out of the saga after the OT. Most of the characters are underdeveloped and the pacing of the first half is all over the place. The CGI resurrection/de-aging of actors remains divisive in hindsight.
However I’ve always welcomed the smaller details and nuances of each movie that make me like them as a whole. What I liked about RO is that it felt interconnected with the wider galaxy. Classical aliens appeared (they were almost nowhere to be seen in the sequels), relevant characters like Mon and Bail played small parts, it acknowledged the prequels, there were direct ties to Rebels, a character from Clone Wars jumped to live action, etc, yet at the same time the new additions, like the Death Troopers or U-Wings, for some reason felt more memorable to me compared with the sequels aesthetic. The grey-vs-grey morality was a welcome change of pace (I also liked TLJ’s approach in this). Most of the time the visuals are majestic. The space battle of Scarif is definitely the best in the Disney era. And it made me appreciate a whole lot more of the events in ANH in hindsight.
I guess I mostly agree with this statement. As others stated, being the best Disney SW film doesn’t say much, so in general, it might be an overrated movie. I also agree that regarding character development, it really doesn’t give you much. However, I had that SW feeling that the new episodes couldn’t give me, even thought they had members of the original cast in it.
As a result, I don’t love the movie, but I also don’t dislike it. It’s pretty well made and has enough highs to make up for the lows.
