I just gotta come out with this very first thought that's on my mind since viewing this mere seconds ago before beginning this review; this is simply amazing!!! The narrative of Samus Aran fighting against the intergalactic threats of Ridley and his space pirates, who're being aided and assisted by Motherbrain and her Metroid horde, not for money, glory, revenge, or fame, but for the man she loves, in order to make the universe safer for him and everyone like him, is very operatic. The music was very much like a modern day Broadway musical, sort of a rock-opera approach to adapting the Metroid mythos for the stage. The animation was brilliant in my personal opinion, and fits the tone and scale of it's source material, yet adds a unique interpretation of the story of Samus through the aforementioned narrative. It also has this Disney/Pixar style and vibe, which tones the dark atmosphere of the setting and other story elements, but is still very imaginative. Worthy of the 5 Stars rating, if you'd ask me. Despite it's Disney feel, it's still incredibly well done. Big shout outs to Osuka and brentalfloss for this collaboration. 10 outta 10!
