Ok Yogi.
I'm not going to refute your points, because they're all valid and somewhat true, but allow me to comment
1. Who cares about farmers? If the movie was called "The Seven Farmers" would anyone have gone to see it? This is about fighters, so I don't exactly care that the farmers were in more abject poverty. The farmers are a vehicle for good vs evil.
2. It's not true that Magnif 7 didn't have any discussion about war. They just weren't all philosophical about it. They were Ray Lewis. Not Homer.
3. The gunfighters weren't after money. Except that one character clearly after the money who kept insisting there was gold in the hills. They were trying to escape or grow up or delay the inevitable.
4. Less tactics. Less paintings on rice paper.
5. You're right. The romance can't overcome class struggles because in real life the samurai thought they were better than everyone else. Anyone can become a gun fighter if you have talent and skill. And then you can go right back to being a farmer if you want.
6. Wise elder was a very minor character. Plus he made a good point. Bullets cost money. But swiping a sword doesn't.
7. The elder samurai were just jealous they didn't take the initiative and didn't want to admit that sucka got served by a non samurai. The cowboys value results.
8. To quote Captain Kirk "I don't believe in unwinnable scenarios".
The reason Magnif 7 is a feel good story is that it's an example of bullies getting bullied. I don't like that guy so I'm gonna pick a fight. The one second where Eli Wallach offers Yul Bryner half of everything and Yul just takes a deep breath, gets kinda p---ed, and tells him to ride on is all the study you need. There's none of that in Seven Samurai. We just assume the samurai are good guys. In fact. The Samurai get p---ed at the farmers and the actual farmers are displayed as the bad guys when all the samurai armor shows up. The farmers aren't the bad guys. The Samurai are the bad guys. This isn't exactly good guys vs bad guys. It's actually bad guys vs really bad guys and that shows up way more in Magnificent 7. There is a distinct point made in Magnificent 7 that Chris has been offered a lot but never everything.
There is a difference between a fun movie and a good movie, but if a movie is more fun is it better?
