I would honestly love it if he gets in situations where he wants to hit someone but knows he can't so it's a build up to when he gets to hit Zod and make it spectacular. Actually they should do this with all his powers, give little glimpses but with the punching I want to be frustrated for him. But when he lets loose I hope I'm like Jesus! and be thrilled and amazed by the power he actually has. I think that is what is lacking as far a Superman goes. Stm had the "you will believe a man can fly!" aspect. Audiences were amazed. Now it's oh look he's doing this or that that's nice. They need to have that connection that people can relate too. Like the point in your life when you know you can or should have done something but didn't or couldn't etc. It needs to have the psychological effect on a persons memory so they can relate.
