It most certainly does not amuse me! I have to actively try to ignore it to enjoy the movie.
Some quick examples?
-Yes, you might be able to "shrink the space between your atoms" to become tiny, but you still have the same mass. So, a 200 lb man would still be 200 lbs, but be standing to tiny feet as small as pin head. You'd be stuck in the floor like a thumbtack! Uh oh! (I do love how DS9 handled, sort of, the "tiny atom" issue when they said they were limited to the amount of air that had shrunk down with them. Still didn't address all that mass on tiny feet, though.)
-Yes, you can catch someone who fell from a tall building in your super strong arms, but it wouldn't be any different than them landing on two pieces of parallel steel poles! Uh oh!
-Yes, you are strong enough to stop a speeding truck, but what you applying your muscles against? You'd just be knocked of the way if you stand in the street and hold your very strong hands out! There are so many examples of super strong people doing things in movies where there was nothing to apply their leg muscles in opposition to the force being applied to another object by their arms. It wouldn't be that hard in many cases to account for this (as in, sometimes the show the hero pushing against railway ties and them breaking as the train/vehicle slows down. Or, a hero holds a door closed against a flood by bracing his legs on the opposite wall or some such.)
I love physics principles (not the math, I can't do the math ) and I am offended when they don't get the respect they deserve.
