I try not to look like I support a theory. Theories are theories. I like to see an factual explanation. However, theories can be expanded upon as well, to come up with another theory closer to an explanation. Therefore, in my view, theories are not useless.
However, I prefer dealing in things explained or proven as using theories make me feel as if I am dealing in something untrue, until the theory is more supported by fact. However, theories can make reasonably interesting films. Here’s my review of The Black Hole (released in 1979 when I was none the wiser). Perhaps this film propelled some into engaging more in the universe and its mysteries and came up with discoveries unheard of before. Films can inspire.
