I get it. I'm trying to think of a movie that I love to watch that's a real stinker to others. Some might say "Fury Road"...
Yup that's one lol.
Here's the thing with superhero movies.
I spent my childhood loving every other movie genre but when it came to superheros I only had my wonderful comic books to interact with.
I would read them with such passion that I couldn't even imagine what movies would be like with them.
Then it happened, STM arrived and it was an instant classic, then we wouldn't get Batman until 11 years later!
11 years, sheesh!
This is why now I am super forgiving of them.
Of course I will embrace, cherish and rewatch the really good ones, your STM, Batman89, Spiderman2, Blade1, BB, TDK, IM1, TWS, CW, Avengers, Logan.
But when it comes to the lesser ones who put in a valiant effort (not your Superman 4, Catwoman) I can't help but think back to my childhood when I could only dream about them which is what informs me to be more tolerant and less critical of their deficiencies.
So yeah sure there are some mediocre superhero movies but honestly i'm even having fun with those.
