I'm guilty of this as the next person.
"That movie is garbage!" I've said it. I'll keep saying it. It's only for effect. I'm just being ostentatious for no reason if to make people react. Kind of the point. But is a movie ever really garbage?
No. Why? Because...
"One man's trash is another man's treasure."
This idiom is as classic as it is male chauvinistic. It's about the subjective. And the subjective is all about art. I love the movie "Butch Cassidy and the Sundance Kid." But I cannot stand the 4 minute "Raindrops Are Falling On My Head" montage. Some people don't mind it. That's fine. I realize it was made in the 1970s, so it's not surprising the song is featured so much. I don't even have issue with the song itself. I just don't like it in the movie.
I'm not the biggest of Star Wars fans. Yes, I like some of the original trilogy. But I stop watching Return of the Jedi after they rescue Han. To me, it's over. Granted, I'm in the minority amongst people my age and older for Star Wars is canon. And good for them. It's a great franchise.
Now, come talk Indiana Jones with me and you'll see where my allegiances lie. There's a current, ongoing "discussion" with some friends of mine about which Indiana Jones movie is best. In fact, the only ranking of the movies I will agree is correct is: 1, 3, 2, 4. But there are some who believe Last Crusade is best or even Temple of Doom and while I love those movies, they are not better than the classic Raiders.
But again. It's all subjective. And everyone is right. We all experience those movies, every movie, different from each other. As it should be. We're being told a story. You may like it. You may think it's just okay. You may hate it. But we're all right in our opinion.
The only final piece I'll add is that you actually have to watch the movie or the TV show in order for you to deem it garbage. I get if you watch the trailer and say, "It's not for me. I probably won't like it." Fair enough. But if you claim a movie is terrible and you've never seen it, that's the definition of being uninformed. Don't be uninformed.
