especially things like science which are not subjective
Perhaps that's because you've heard people like Dartagnon bleat on about opinions and subjectivity so much with regards to games that you now honestly believe anything that skirts the edge of art is somehow completely subjective, just because it contains some art?
Film is a very specific medium with its own rules and science for which a vast amount of it is pure objectivity. The subjective only comes into play if you narrow your field of vision to facebook-like binary like/dislikes. If film didn't have objectivity then you simply wouldn't have Citizen Kane regarded as a masterpiece and Steven Segal regarded as a mockery.
The subjective aspect of Citizen Kane versus Steven Segal is simply whether you were entertained or not, not whether one is factually better than the other, one is quite clearly factually better. However, even those that found Citizen Kane boring and find Steven Segal entertaining are, if they are rational beings, able to acknowledge that Citizen Kane is a better movie, but they prefer to watch "dumb" entertainment, for whatever reason.
What is remarkable about this new Star Wars movie is that it is factually a huge improvement over the prequels with regards to presenting a sequel in keeping with the original franchise. It is factually a "dumb" movie designed for pure entertainment, just as the originals were, and it was the failure to entertain while being dumb that makes the prequels, again, factually worse.
Now, how some people are even going to the cinema and expecting "something more" is really quite astounding. To go to a movie like this and expect any kind of 'depth' is one form of irrational, but to come away from it and complain about a lack of depth is beyond idiotic, and this has nothing to do with the subjectivity of the individual, this is factual false expectation from an irrational mindset.
The movie was a top-grade dumb movie, as I originally stated on the first page. It's the best a dumb movie will ever be bar abnormalities such as Robocop, Alien or Die Hard. It's on par with The Avengers, Jurrasic Park, James Bond and all the other top-grade dumb movies with the usual load of natural imperfections. Factually. The only subjective is whether it entertained you or not, and if it didn't you should still be able to acknowledge what it does do extremely well while expressing why you were not entertained.
Because without objectivity no-one would even watch Citizen Kane. Without objectivity there's no point in anyone with an interest in the art of movie making taking the blindest bit of notice of your inept understanding of the medium, you're like Homer Simpson being allowed to design his perfect car.
TL : DR for Pibbur: I met a bloke today who had no idea War and Peace was a book
