If they would've shot the whole movie in Krypton it probably would've been a decent movie.
The problem with Superman as a character is his stomping ground is regulated to one City (as is Batman). DC tried to basically recalibrate the entire story (which was a great idea), they just did a sloppy job.
I actually could've done without the whole Krypton backstory,especially if they was going to have Jorel give an explanation of things once Clark found the ship,matter of fact I may have preffered not knowing Zods intentions right away when he showed up.
I actually think they have done a good job of having superman act outside of one city,and you cant really make that a complaint can you?Superman gotta have a home base too
