Michael Shannon looks goofy with his evil beard. It looks like it can be fine. The look of Superman (actor and costume design) is really great. Overall the cast is pretty great. People are so willing to sign onto these comic movies these days, for better or worse.
Superman as a kid is boring. Existential crisis Superman and Peaceful Alien Introducing Himself to the Earth Superman look interesting. The part where he has to punch Michael Shannon, I dunno, I guess he needs someone to punch in the movie. Could have some nice action to it.
And it's already more entertaining than Superman Returns. Creepy Stalker, Home Wrecker Superman is boring. He ruins a cool plane to save some humans at one point. When he's powerless, he cries out "I'm still Superman!" And his costume made him look like sky blue flavor toothpaste.
