When I saw the movie I did dislike it a lot and now that I have had time to sit and think about what really bothered me, a lot of my problems really focus around the final act of the movie. I might not like some of the choices in the first two or question how they make sense in scheme of things, but they don't really bother me.
Really its about the choices (or the film makers lack of showing us) what Superman is really doing during that final battle with Zod. Show us the buildings are empty with his heat vision or hearing, have him think of another way to deal with Zod, just something to show us that he really still deep down has that kind of thought process that the first parts of the movie try to show us being instilled in him I think would have gone a long way with me at least.
