Two things--first, I agree with Motuxmen, god help me--opinions aren't facts and saying it's "a fact" that this movie is bad is just wrong. A movie (or a book or a song or whatever) is either good or bad in someone's opinion, not as a fact.
But no, your kneejerk anti-Marvel argument is pretty silly. I don't think the people who have seen this movie and legitimately thought it sucked had any trouble following the story, other than the blatant out of left field Crisis references that are for comic book historians only. The story seems to have lots of plotholes and some shoddy character motivation and no amount of "But Marvel fans are stupid!" will handwave them away.
No anti Marvel argument from me, you are putting words in my mouth.
Most of the people who disliked BVS claim major plot holes (as you just did) and a story that is hard to follow.
They never elaborate on any of it, it's some kind of accepted doxa for them.
That's what I denounce in my post not Marvel, I like some of their movies.
