I really would love to watch a modern Superman movie where we get to see a little bit more of the Clark Kent persona and Superman taking on a less "apocalyptic" threat. Bizarro would be cool too. Just let the audience hang out with the characters. Let them experience the Metropolis lifestyle and what kind of impact Superman has on it. Show us Superman doing Superman things. Even if it's just saving a cat out of a tree. Not everything has to be catastrophic. Explore his social relationships and show him being an active crime fighter. Don't be afraid of making him simply investigate a crime. Do something different, but at the same time recognizable as a Superman story. Not everything has to be about saving the world against aliens with a big, boring, messy third act. Make a smart movie and don't go formulatic.
This is basically what i wish for a Superman movie. And if they use Bizarro, make him funny and dangerous at the same time. That would be perfect. Don't just go the evil clone root. Make him more complex.
Is it asking too much?
