I agree with this, however i do think the movie could have worked like it is. Since Batman is the best known comic book character, you can skip a lot of backstory etc imo, even "normal" people know quite a lot about this character. So its not "absolutly" necessary to give him a movie to build him up i think. But yeah, it would have done wonders to establish this all and would have helped make the movie tighter and far less overloaded. To me Personally, Superman is one major thing that broke the movie in terms of Story and character. I have such a hard time seeing this character as Superman, as somewhat of the opposite of Batman. There is a difference to me between a darker approach and a downright depressing one...and this Universes Superman feels simply depressing. Which is a shame since in its core, this Movie Superman has potential. The Other thing is simply that its overloaded to create a base for a Justice League movie and stuff. I still dont get why they wanted to catch up with Marvel so fast...why the rush with it?
