My list of essentials would be:
-2. Lois Lane endgame
-3. Clark working at the Planet, or in the news gathering field in general just works.
-7. Secret identity. Kal-El should retain his Clark Kent persona.
-10. Planet supporting staff, even if Clark is not always with the Planet Jimmy and Perry should still be trusted allies.
4. I wouldn't be super strict about Kryptoians popping up from time to time. Things like New Krypton are fine for a period. (in retrospect I probably should've voted for this one)
5. I would keep Superman's powerset as is, but I wouldn't be opposed to him picking up a new power or two if it made sense and wasn't stupid.
6. I wouldn't mind Clark leaving Metropolis for a period to mix things up. You know Metropolis is his home but Superman's turf isn't limited to the city, he'll always return to Metropolis in the end because that's his home-more so than the Fortress.
8. It's been interesting to see Luthor become more of a gray character. I wonder how long it will last before he goes back to the original recipe.
