I liked the detail of the Emerald and that they were inside the ruins in the best style of the game that if I did not expect it at all. It's super nice and you can watch it with the whole family without the need to be in the same vein with the Sonic character, that's great and I think it's one of the movies based on a video game that does better and not only for its graphics and popularity, but for the message it leaves and we see how Knuckles creates a false desire for revenge when in reality he does not understand the reason for it since it is not part of his present but of the past of his family and that perhaps they did not understand and collides with that reality when he tries to fight with Sonic, but he realizes that he does not want it because he does not understand the reasons for that war.
It is a powerful message that perhaps not everyone, especially the youngest ones, can see, but it touched my heart.
