Of course he's not, he's in Justice League: Part One (and presumably the other ones as well), but wouldn't it have been nice to actually have some time to mourn and to at least pretend to accept his death? His death follows the same pattern as everything dramatic in the film: it lasts only as long as someone with ADHD can possibly commit to. Isn't this also just the end of X-Men: The Last Stand, where it's suggested that Magneto's powers are definitely all gone forever right up until the point he somehow just heals with no explanation? Hopefully, we'll get the (hokey) explanation that Superman actually just went into a Kryptonian healing sleep (which Zod was obviously somehow not able to), but it still smacks of that immediately retconning approach to storytelling.
