Its not just writers he is insulting. Its the audience. I love this new narrative that BvS apologists are running with. "Its too deep for audiences to get." No. It isn't. I get every theme of BvS. I get every heavy handed, melodramatic, double-entendre that comes out of Lex Luthor's mouth. There is nothing deep or intellectual about it. The themes are not hidden beneath the surface. They are all surface level and beaten over the viewer's head with the subtlety of a high school student who is preaching about philosophy. There is nothing complex about this movie. Its not 2001. There aren't hundreds of little, hidden messages, themes, etc. I got everything. The problem isn't that the audience is missing Snyder's point. Its that Snyder's delivery of the point just isn't that good.
As a hard-core DC fan I can't bring myself to apologize for B v S, at first I kind of liked it, but the more I thought about it the more upset I got.
I agree with what you're saying about B v S, really the whole "it's too deep for audiences" isn't the problem. It tries to be meaningful, but really is just a mess !
Anyway, the real problem is that it's not entertaining.
It certainly is possible to be deep and still be entertaining. The Dark Knight is deep, dark and deliciously complex (well except the not-so-subtle foreshadowing) but anyway it's SUPER entertaining. Snyder's execution was awful on B v S, and that's why it's so lacking in entertainment value.
While there are bits where Batman comes off looking cool, I suspect that has a lot to do with Affleck and those on-set re-writes.
If Snyder had cut down the mess, chucked out a couple of subplots and focused on solid character interaction and development, punctuated with well-choreographed and exciting action sequences.....well then he couldn't have gone wrong.
To be honest, B v S may not be as bad as the critics make out. But, it's not that much better. For me, it is a far greater failure than Spider Man 3 - because it promises so much and delivers so little. Henry Cavill's workout videos on facebook are better shot than his scenes as Superman - will he become a great Superman ( thought he was good in MOS) ? We might never find out because ****ing Snyder won't give him any lines or any decent interactions with other characters that last more than about 10 seconds - the only exception being the bathtub scene.
Anyway, if it had been done in an entertaining way I could have forgiven a lot of the rubbish in it.
