I can believe that at his age 25-30s Batman is a grand master of many different forms of martial arts
I can believe he is the worlds greatest detective
I can believe he is a master of meditation and whatever the hell that spiritual thing Morrison was talking about on his run
but
Its just pretty hard for me to believe he is also a supergenius that design, build, tested and successfully developed: a flying car, a giant mecha robot, a boomerang that returns to himself on its own, a mask that creates a hologram to disguise himself and all his other fabulous gadgets
not only to mention that he help build an A.I. that can take over the world
Its not that I dont think he should be smart, is just that there is a point where it just becomes too incredible to accept which is why somethings like Batman Earth One or the Dark Knight movies delegate those things to Lucius Fox and it kind of works there
so should Batman be a scientific genius?
