Oh yeah, they left out all kinds of key tools and even subplot (Lex Luthor was supposed to be an old friend/turned enemy of Clark Kent) and that aspect would be used for more dramatization as Superman is already clashing with Batman.

That's an excellent remark about The Dark Night, it is as if that movie and the Dawn of Justice one comes from totally different planets.

Take the depth of the villain for example, on one side we had Bane, and we had the Joker (from the other Nolan's Batman movie)... In Dawn of Justice, we have this:

" I smash!" haha... That's the storytelling depth of the arch-villain that they all assemble to fight.

Btw, you got a great point about cutting too much of the backstory out. I may even add Suicide Squad there, since they fast-forwarded through some awesome stuff.

Thanks for the awesome and engaging comment!!
