It’s neither.
I disagree. It’s both.
You cut the rest of the paragraph just to disagree. I meant it’s neither on its own as it is both.
But you can see it however you want it to see. Some people say it’s a western (well, at least the first one) while others think it’s some deep religious film which has some weird father-son psychology layers where a man needs to confront his father to become a man or something (I’ve heard this angle before and it’s a stretch - I mean, it has that element but the analysis of this went way deeper than I could explain here. Just pointing this out before someone says it’s exatly that.).
