I watched Uchuu Kyoudai back when it was airing and I was hooked on it from start to finish. It took me a while to find this movie but I'm glad I did. Judging by the name of the film, I thought it was another re-telling of the OVNI scene that got the Namba brothers dream of space but it isn't and I was thrilled to be wrong. This movie tells the story from the aftermath of the OVNI scene up to the moment Mutta headbutts his boss and so we get to see a lot of Mutta's and Hibito's backgrounds and journeys up tothe start of the anime series. It was beautiful and emotional.

The animation is on the same level as the one present on the anime series and the only thing I'd change is get rid of CGI because it breaks immersion for me.

The sound design is solid. We have the original OP and most of the tracks played throughout the movie fit the whatever is going on at any given time. If it were up to me, though, I'd change the 2 last songs that played.

All things considered, this is a gorgeous movie that gets a 10/10 from me.
