Yeah, I think Marvel went into panic mode and tried to save face as much as they could. But, if you ask me, obliterating a multiversal threat that easily was so stupid. I mean, recasting sounds so much more natural than bringing your 60 yrs old Phase 1 icon back like a Tony Stark variant - or something like that.

Just think about it. The Kang army, all of his knowledge and powers, his connection with Reed Richards. So much potential wasted.

And yeah, Boyega would have been great as Kang.
