Again, it's ultimately about how it makes you feel on its own merits, not how much enjoyment you get out of it based on what you yourself know (even though it can certainly help), or what someone tells you based on research afterwards or beforehand.
That can be just their own take on it, and is in no way more valid than anyone else's, no matter how scholarly they seem to be about it.
It's entertainment, its sole purpose is to entertain and be successful financially for its creators. If it succeeds in both, it's great, if not, less so great.
Who cares if a movies is objectively great (technically flawless, for example) if you just don't like it, or vice-versa?
It's your own taste, it's your own time, it's your own money, and you're your own person.
What you think of it is what counts.
This recent idea that you need to explore something to death in order to enjoy it is ridiculous.
Like, why would you care what exactly went into making a meal that you ultimately don't find appealing? It's not gonna make it more appetizing if you simply knew Gordon Ramsey made it, will it?
Unless of course, you're a snob, which obviously you aren't.
Same thing here.
