Good response. But.
(making a crooked analogy so I don't spoiler)
What if Superman had lived in fear of K foreva, NOT because he had actually experienced the bad effects, he had just been told it would be bad news and he believed it.? That would be super sad, a life unlived due to ungrounded fear.
I also thought how that was all brought to light was simplistic but cute nonetheless. I've seen worse.
Then I would have to convince myself that a guy with above average intelligence wouldn’t ever accidentally receive some sunlight or gaze at a cross and never notice once that he wasn’t on fire. I couldn’t. And then when he does learn of it, his response is to off himself? Otay.
Just my opinion.
