I didn’t realize the potential Rogue One had until I saw what Tony Gilroy was capable of doing with Andor. It really puts Rogue One in a different light. I always thought Rogue One was mediocre. The main problem is the pacing and the characterization. The movie jumps around too fast (especially in the beginning) to really let any of the events resonate, which is a common problem with modern movies. Also, Jyn Erso and Cassian Andor just came off to me as way too under-characterized. We needed to spend more time with them before the main events of the film, in order to get a sense of who they are. I could see some bare outlines of personality and chemistry in Erso and Andor, but not anything close to Original Trilogy levels. But now that I’ve seen Andor, which has amazing characterization, Rogue One comes off more as an imperfect, missed opportunity, rather than something hopelessly mediocre which I can just write off.
