It was if someone watched Gurren Lagann and decided to ape it without understanding the show, which is absolutely fucking baffling given the creators. What even was this plot? It feels like they had specific scenes and frames in mind and tried to shape the plot around it to draw those out without rhyme nor reason.
The fights were manic, the colors were gorgeous (at first, it became obnoxious later on), the music pretty good. If you like watching characters stand around and give plot exposition (because fuck actually writing), then this movie's for you.
