Same, Vortex. It's hard to pin down because as you go through Corenswet's features one by one everything should work, and his face isn't actually that dissimilar to Henry Cavill's. But in the end the appeal just isn't there. I'm pretty sure it's something about his eyes.
I will say that in other projects I've seen him project the gee-whiz Jimmy Stewart wholesome aura that's needed for the character.
