'Superman Returns' Writers Not Returning

Superman Returns writers Michael Dougherty and Dan Harris have decided not to come back to write Superman Returns Returns, leading to questions of if Bryan Singer will still direct and leaving Warner scrambling to take pitches from other potential writers. Here's what I've come up with:
- Lex Luthor shoots a special beam into the ocean that radically increases the number of great white sharks, while also giving them Kryptonite teeth. Superman has to fight these sharks, frequently employing a technique where he spins one shark around by its tail, using it to hit other sharks.
- It's discovered that a Kryptonian great white shark, orphaned like Superman, was raised by Earth sharks. Superman has to stop this shark's bullet-speed ravaging of a public beach, but it's hard because it's a Supershark, making it the equivalent battle of an Earth guy fighting an Earth shark. Very humanizing.
- Superman loses his powers, then has to fight a shark.
- Superman finds a new supervillain terrorizing the city with his giant teeth, massive size, and fins.
