eh, reign of the superman I thought was the weakest part of the death story.
You need to go watch Doomsday again

. Clark is going to Afghanistan to do foreign reporting as a cover to why he won't be around while Superman and Lois have a vaccation (though I do admit, I didn't like the idea that Clark still hadn't revelaed him self to Lois at this point). The cancer thing was Superman trying to cure it while lamenting that he can create a machine which can make contact with the future, but he still can't cure one of the deadliest known desieses.
And come on, they're dating and obviously having sex. You think Supe's isn't going to be fooling around and flirting in private?
The film I'd like to see is Flash, or maybe even Aqua Man (though I admit, I've never been Aqua Man's biggest fan). I mean, they've done Superman and Batman to death, they've done GL, WW, and the JL. But you have an amazing, classic character like Flash and they just seem to ignore him.
