Spoilers for MoS and STID to follow...
Very puzzling, especially given the fact MoS also
rehashes a villain with previous big screen exposure.
Or, maybe not so puzzling, if we're willing to at least consider the possibility MoS rehashes Zod in a better way than ID rehashes Khan? *slaps self for even thinking such blasphemy*
Would taking the time to fill in all the Khan back-story, even if they totally retconned it, made it longer to compensate that time taken, have better resonated with audiences the way MoS seems to be doing?
