The only strong complaint i can think of right now is...
Spoiler:
The portrayal of Johnathan and Martha Kent. Sure, the death of Johnathan was well done as was their performance. However, I think the movie focused a lot on how Jor-El influenced Clark Kent to become Superman as well as creating the Morale compass for him. Honestly, that should have been dealt with better, the entire movie we get this idea that Pa and Ma Kent want Clark to be in hiding, to hide his powers. Heck Johnathan dies because of his belief. Clark does go into hiding until he meets Jor-El.Not to mention the entire, "you're not my dad" felt like an exact copy from Spiderman.
