Rhea Gall Force is a 1989 anime OAV film which is set in a bleak future where humanity is on the verge of extinction after resurrecting an alien life force hidden inside the Moon. The film follows the last remaining human soldiers as they fight for survival and a desperate chance to escape to Mars. Will they succeed in saving humanity or will the aliens take over?
The film is quite gritty for a short anime and its post-apocalyptic setting and the conflict between humans and machines creates a compelling backdrop for the story. The main characters, though somewhat archetypal, are distinct and have their own motivations. Sandy, the hopeful young soldier, is the epitome of spirited and hopeful young lady who seems to draw people to her with her earnestness and honesty.
The animation is striking, with detailed character designs and impressive mech battles. However, the film suffers from a slow pace and some clunky exposition. Also, the dialogue and character interactions can feel a bit dated and stereotypical at times but it is a product of its time and, once again, isn't too egregious even with our modern sensibilies. Sure, there is the obligatory gratuitous shower scene for no real reason but unfortunately that was late 80s anime.
Overall, Rhea Gall Force is a visually appealing but flawed OAV. It explores themes of survival, hope, and the conflict between humanity and technology well and despite its shortcomings, it is an enjoyable watch for fans of mecha anime and post-apocalyptic stories.
