Re: Kill The Kryptonite
I'd rather avoid it AND Lex in the early going if at all possible. Kryptonite has been a plot device in 3 of the 5 previous films, and Lex was in 4 films. Yeah, I know MOS is a reboot, but even so I'd prefer not to overuse both of those wells, frankly.
If Metallo shows up I'd rather he were a byproduct of salvaged Kryptonian technology/metallurgy, capable of hurting Superman just by beating the **** out of him.
