Redline is totally my kind of thing. Loved it from the opening of it. Space Pirate captain Harlock was another great movie with high budget and a terrible box office record. I really loved that movie. Since you consider ending to be paramount you might have problems with BLAME! Godzilla: Monster Planet and maybe even Gantz 0

Personally I liked all of them. Space Pirate Captain Harlock was probably my favorite out f the bunch. Really sad to see great movies never getting enough recognition. I personally prefer those barely any screen time given archetype based characters or some exposition and technobabble heavy mindfucks.

Basically Gurren Lagann or GitS/NGE/Anythying by Urobucher
