Uchuu Kaizoku Captain Harlock, Tengen Toppa Gurren Lagann Recommendations
Space battles in massive ships. Space Pirate Captain Harlock is one of the many sources of TTGL and Simon's design in the final part is actually inspired directly by Harlock. It is a lot of fun and great to watch and note the similarities with today's animes. Harlock was (and still is) a very influential anime.
