It is neither science fiction, nor a movie (in the fiction sense). It is a documentary, and as for the science fiction, it isn’t present, and not in the same way that it isn’t present in some of the other movies.
It isn’t there because it was not the intention to make a science fiction movie.
What the bleep do we know was meant as non fiction. You were meant to take it seriously, as usable information.
None of it is actually real, though, and it is filled with pseudoscience. But at its core, it is meant to be watched just like a any other documentary, not as a movie.
