I'm sick of evil Superman too. Like I said, I sorta-kinda want to see a Dark Metal Superman "against better judgement."
We have definitely seen too much evil Superman in recent years, but BWL goes to such crazy extremes and is so over the top and unapologetic about what it is.....it's fun. And the metatext is brilliant. I wouldn't be against the idea of a Superman who's allowed to be as capable and crazy competent as BWL and dives into the same kind of meta, as long as he also rocks a James Hetfield style mustache. If BWL is the Dio era, I want Metal Superman to be Justice For All (or better yet, the more ridiculous Re-Load or S&M!) Metallica.
