This movie is in no means perfect, it has its flaws, the pacing is way too fast, the dialogue is lacking, and the animation is basic, though it has its good looking moments.
This movie is however a good story, it managed to touch my heart a few times and does what I would call a good job tackling the themes of parenthood and challenges with communication.
The characters weren't the best, I do like Lord Grigon for his few moments was fleshed out and characterized the best in the movie. I would have liked if we spent more time seeing his and Olga's perspectives just as parents, as I feel Olga definitely needed it. Elio himself was a rather basic character but that doesn't mean bad, for his movie he works, I feel his characterization could be improved however its not bad. In my opinion the Clone is the best, its really just comic relief and I find its few scenes where he chops off his finger, response to getting punched, and when he said "you made a friend!" to be quite funny, overall a character who made me chuckle and that's good.
Four moments in this movie are notable and quite enjoyable other than previoudly mentioned. The starting with the Carl Sagan Golden Record interview was well used, it works well and wasn't over used, its also just sounds nice to the ears, I quite enjoy when movies have real world interviews. I found when Olga and Elio exited the debris field that Earth looked really good, so props to the animators for making it look like that, it was actually quite pretty. The ending when Lord Grigon tore open his suit, honestly it had me by surprise, not because its a twist but because its a really nice moment, and his moment when he shoots the clone they're good character moments.
