Are you kidding me? That's just stupid!
When you're reading a comic and you come across a particularly impressive feat - regardless of whether it's accomplished by your favorite character, least favorite, or by someone you're totally indifferent concerning - at what point do you take a step back, stop suspending disbelief and just utter to yourself "Now, that's just dumb"?
Regardless of whether it's moving planets with giant chains, or some of the weird pseudo-science explanations for the way technologies work, whatever it is.
Where does disbelief resume?
