If this film had actually been written well...
It would have easily made a billion, gotten rave reviews from critics and everyone alike, no studio meddling, and we would have had a very successful film franchise on our hands.
But nooo, fanboys want to play the blame game. Pinning everything on Chris Reeve Superman fans/REAL moviegoers, and the studios for not letting Zack Snyder continue his vision. If we had let Snyder continue his vision, we've would of had half-assed written films that underperform profit-wise. Fanboys would be okay with a half-assed written film as long it ticks their boxes of what they want out of a DC film.
Lesson here, make a GOOD product that everyone will like and it will be successful, blame the director and writers for how your movie series turned out!
