A lot of people are commenting now that Star Wars isn't sci-fi because there's nothing about it that's actually scientific.
It's just futuristic fantasy, they say.
Star Trek tries to suspend your disbelief by maintaining an air of often-bogus scientific authority.
If you had true science fiction; you couldn't travel to another solar system within your lifetime. That's the science as we understand it.
Science Fiction would make for difficult, uncomfortable viewing and not escapism. Interstellar is an example of that. I very much enjoyed it but did not make easy viewing.
I think anyone that thinks it has to be hard sci-fi to be sci-fi is kidding themselves.
