Finished this one and…I think if they were each separate Elseworlds stories I would have liked it a lot better. As is, I thought the alien dude’s motivation was really dumb and convoluted. Like, okay, he wanted to use Superman to save his world, but he didn’t want other aliens to know about his homeworld. Okay…so why did he need to put other memories in there? Couldn’t he have just mindwiped him in the first place? And then in the end, it doesn’t matter because a bunch of other Earthlings (and one Martian) went to their world to pick Superman up anyway, making the whole story completely pointless.
I dunno, I just wasn’t feeling this story at all. Yeah, it’s evocative of a silly Silver Age story, but the fact is you really can’t do that kind of story without really doing your A-game, because frankly our standards for storytelling had greatly increased even in the 90s, let alone in the 2020s.
