The DC Universe has either had a hard Reboot or simply "shifted" to be viewing a differant universe at least once a decade.

And Batman gets more over the top with each one while still being treated as a street-level hero in his main titles.

Part of the reason that Stark and Richards get away with so much crap is that Marvel doesn't throw out it's entire canon every 5-15 years, which means that Stark and Richards have much more history to draw on for precedence than Batman does for when they pull crap out their butts.

Hell, if anything, they have the opposite problem: Reed Richards once proved the existence of the After Life and built a device that allowed him to physically travel there for the sake of ressurecting The Thing who had been killed off in an earliar storyline. While in Heaven, the Fantastic Four beat up a couple of Angels and met the Abrahamic God who ressurected Ben for them on the groundsthat there was more Ben needed to do and he was only ever "visiting" Heaven.

After scientifically proving the existence of the afterlife and of the Divine, people are more likely to call bull when he can't science up a solution(Like how he couldn't fix a gunshot wound in OMD.)
