What an arse *spoilers*
So Superman saves the Kandorians but just drops them off on some desolate wasteland of a planet with a red sun? What an ass. Not only do they not have their powers, but now they're living in a wasteland.
Why not let them come to Earth? Selfishness? Hell he could have dropped them off on the moon, at least they'd have their powers there.
He specifically picked a planet with a red sun, what was the point of that? Just to be a dick?
