People give Batman way to much credit after Nolan's Batman trilogy.
No almost everyone that said batman has said we are basing it off comics......superman and spider man fanboys said lets based it off movies
And batman still wins.........once again his prep skills, knowledge, resources, etc are almost his super powers.....don't get it twisted and think batman in the movies is a fraction of the real batman in terms of talent and skills
Batman made a battle plan for every superhero in case they went crazy/rogue and if spider man and batman lived in the same world then batman would exploit his weaknesses for battle.....so Spider-Man is weaken against certain chemicals...batman would analyze it and keep it on himself or around just like how he analyze superman once he became aware he was in his world
That's what you people don't get.....batman prep, knowledge, resources, detective work even works apart of himself that NO other super hero presented Spider-Man, superman or wolverine can even come close with
And to the guy that said batman lost in The Dark Knight Returns....let me explain.....batman FAKED his death and even then batman was a old alcoholic that lost everyone close to him so he didn't have much to live for and superman only went after batman due to the govt cracking down on superheroes........
