I noticed after Justice League came out, that some of the Snyder diehards were upset about the bit where Superman rescues an apartment full of people by actually lifting the whole apartment and flying it to safety. After all the hard work Snyder did to make a realistic Superman who abides by the laws of physics and makes you believe Superman could really exist, Joss Whedon came in and ruined it all with his silly cartoon garbage, they said.
There was a time when Superman lifting a small building was considered a reasonable feat, such as the post crisis era. Superman's powers were reduced from where he was able to move planets with his bare hands to lifting cruise ships or a big chunk of land. But at some point or another, even that has come to be regarded as stretching the limits of people's suspension of disbelief. Every few years, people expect increasing amounts of realism so that what was once considered realistic in one decade is considered laughable in another.
Why is the endgame for comic book/superhero movie fans ultimate realism? And why does it seem like people expect more of Superman than they do other popular superheroes? I mean, a hammer that can only be picked up by a maybe-god or people who are "worthy", and can be spun around by a leather strap and used to sort-of fly and can also summon lightning? Or an invincible metal that can absorb any impact, no matter how powerful? Or a power suit that protects the wearer so well he can fall from the sky and come out with barely a bruise(because as we all know, people can go flying off a cliff in a car and come out unscathed). I'm not necessarily criticizing any of those examples but it just shows the extremes of suspending disbelief that people are comfortable with while simultaneously nitpicking every little thing about Superman.
I get it that lifting heavy objects is something that the average person can relate to and understand the physics of more readily than the more out-there super-science of the Marvel universe, which is probably a lot of the reason why people are always going "Hey, you can't lift something that big and heavy without it breaking!" while nobody ever says "hey, you can't shrink people by moving their molecules closer together!". But what I don't understand is why can't people just accept that ability to lift exceptionally large objects as a facet of Superman's power, whether it's explained as a form of telekinesis or something that's acknowledged by bystanders but still treated as a mystery.
