Star Trek is true scifi? I always considered it to be soft scifi due to it being more about social issues in space rather than the more hard scifi about the fictional science. At least the book of Project Hail Mary is closer to hard scifi than Star Trek as they spend a lot of time describing the science. The movie rightfully skips most of this tedium in favor of a beautiful spectacle.

This is the first time I've heard of the idea of "true" scifi though.
