Yeah, BvS was definitely not made with mainstream taste in mind, I would say. Or certainly it does not cater to, or pander to, that taste. But that said, I do think it has enough captivating character moments, action scenes, and cinematicgraphical and musical score ingredients for mainstream audiences to thoroughly enjoy it, though.
Imo to really appreciate how layered with symbolic meta-content BvS is, one has to understand what deconstruction is. And in that aspect it certainly helps to become familiar with that topic, i.e., deconstruction, and to self-educate oneself about it. Ideally, this should entail understanding the roots of deconstruction in the comics, particularly 1986’s Watchmen and Frank Miller’s The Dark Knight Returns.
I’m a bit sorry/not sorry about how elitist that probably sounds. But it is what it is.
