The pacing was great, the character moments were great, the plot was interesting with having to change little things again and again to keep history the same. It was really great and the best moment was the final scene which unfortunately for me was ruined a little by the pop song. Yes its a nitpick lol. But come on. Narratively it works well but I wish they would have gotten rid of that song, especially considering the score was quite excellent throughout. But that's my only gripe. They also handled the political side better than I thought, especially with saying that change has occured and the world is better off.
