I take each film as an individual object. I couldn’t care less about Superman either but think that the Richard Lester film ‘Superman 2’ is a minor masterpiece.
I’m not sure I ever successfully watched all of Superman 2, I know I’ve seen parts of it, hated it. Before I even realized my dislike for the character. Actually it was one of the pieces that helped me realize not all movies are for all people. There is simply not a Superman story that will interest me for 2 hours. I have the same kind of thing with Rockie, I know the common wisdom is that’s the greatest sports movie ever made, bores me to death, never seen any of the sequels. Creed’s getting great review, but I know I’d just hate it, so I skip it.
