Kneel before Zod.
Based on FR's movie-prediction track record that statement probably means the movie will be a huge success. Even Avatar, before its release, was predicted to be a huge failure on FR before going ahead to gross over a billion (talking about 10 figures, I predict a billion as well for this movie once everything is added together. Consider that Man of Steel grossed a global tally of $668 million on 14 weeks).
Predictions aside, I'm not too sure that people want their heroes as they used to be. People have lost something over the last decade or so, and many of the 'modern heroes' couldn't pass muster twenty years ago. The inverse is also true, with many of the pure white-hat heroes of yesteryear not making it today. Think about the first Superman movie starting Christopher Reeves. A truly wonderful and superlative movie, with some scenes that are simply wonderful (eg where Superman takes Lois up into the clouds, and Louis has her monologue/soliloquy where she wonders if he can 'read her mind'). Wonderful wonderful movie, but if it was released today it would bomb. Not enough violence, not enough gore, not enough action.
The Superman vs Batman could be filled with 2 hours of Teletubbies dancing, and the mere fact that the title states 'Superman versus Batman' would guarantee that it would be a commercial success. Even if we ignore modern heroes with feet of clay versus yesteryear's golden gods, that movie is guaranteed success. But if we take the money out of the equation, I am still of the opinion that society has sufficiently changed that the modern hero is, at best, the anti-hero of yesterday.
Who knows, maybe in another decade or two it will have shifted from yesterday's anti-hero to yesterday's villain. Maybe you'll see a movie with General Zod as the protagonist!
But this movie will make money hand over fist, simply by its title card alone, even if it was simply a two hour montage of Mayweather 'fighting' Pacquiao and Romney 'fighting' Hollyfield.
Kneel before Zod.
