Another product of the time I enjoy even though some don't is the very loosely based
SF New Century Lensman anime, released in the US as
Lensman: Secret of the Lens. Very loosely based on the 1930s-1940s era pulp space opera novels of E.E. "Doc" Smith, though it skews more in a Star Warsian direction. Main character from the novels Kimball Kinnison is a veteran agent of the Galactic Patrol and one of the elites who wields a Lens of Civilization, which grants their users powers that vary from person to person and serves as a forgery-proof form of ID. In the movie, he's an eager but naive teenager who has the Lens thrust upon him, and it more or less gives him Force powers. His friend and partner Buskirk is reimagined as a burly, hairy humanoid, his partner Clarissa is changed from a rather tough woman of action to a rookie who looks a bit like Princess Leia, etc., etc. Sci-fi purists in both Japan and the US hated the liberties it took and how it excluded the science and physics aspects of Smith's work that went along with the space fantasy, and Smith's daughter kicked up a lot of dust claiming the movie was illegally made without her or the Smith estate's consent. The Smith estate did sell off the rights to adapt
Lensman, and the court case was tossed out on a technicality.
All that said, it's a fun romp.

Now, another pulp science fiction property that enjoyed some popularity in Japan was Edward Hamilton's Captain Future, about space-traveling scientist and adventurer Curtis Newton who. with the help of his professor mentor who's been a brain living in an atomic powered life-support system for a while and the two robot pals created by his father, fights villainy throughout space. Toei produced a 1978-9 53-episode series that adapted thirteen of the stories and they were shockingly faithful to the original tales.
