As the entire Majestic Prince saga was completed with the movie release, I highly recommend watching the entire series. It's like the the more bombastic and wild mecha anime of the past, but for the 2010s and no filler for its length. A main cast of underdogs you want to cheer for and follow backed by a large cast of supporting and minor characters that are utilized properly. As mentioned there is no filler, the timeline and setting of the impending and intensifying alien invasion constantly moves the show forward along with the character development and plot at a consistent and enjoyable pace. The usageof 3D is incredibly well done and excellently produced, used only for the mecha and spaceship scenes, and still holds up very well. Overall, it is a fun mecha action show with a straightforward plot with great and well deserved moments and payoffs. Also, one of the rare shows that use the mecha rival team trope in a fantastic way.
