The Superman who punches down isn't the Supergod yet. Once he increases in power, he is naturally going to reign himself in more. Like he did after the first arc in the New 52 once he started flying and being more powerful.
Just like the original Superman, who wasn't God-like yet. He didn't spring into existence exactly how you prefer him. He also didn't necessarily evolve or progress. I don't see how he could naturally when reboots are involved. And COIE involved a reboot and chucking 50 years of history to change him into something else that was perceived as being needed at that time.
The generation that grew up with the Big Blue Boy Scout is no longer the current generation. There are younger generations out there now, and Superman needs to change with the times What worked back in the 70s and 80s might not work now.
If the Superman you like replaced other versions, why on Earth can't he eventually be replaced? Before the big Blue Boy Scout, there was the Champion of the Oppressed, and the Man of Action, and the bizarre Super God. There is no reason those things can't come back or even for a new take to emerge. You're just playing favorites, as all comic fans do, but a movie based on any of these takes would still be Superman.
And with statements like this, you pretty much are proving that you didn't. Or are applying what you didn't like in MOS to the entire New 52 era, because it definitely doesn't show up in the main run that actually matters.
Actually you're the only one who is deflecting way from that take, I think because it flies in the face of your arguments. Films usually draw inspiration from certain iconic stories and runs, they don't really draw inspiration from an entire era regardless of who wrote the content. Like STAS drew inspiration from the Post-Crisis era, but didn't copy every single detail. People suggesting a take like Morrison's New 52 run are necessarily suggesting filmmaker's take inspiration from EVERY comic from that five years. And if a filmmaker just looked at that run, they wouldn't use the "cannot relate to humans" bit because he was very human in that run despite his Otherness.
Also, it's not like contradictory takes between writers is a phenomenon that only exists in the New 52 era. it's all over DC and Marvel's histories.
