But see to me, that right there is one MASSIVE "what if?", almost the point of rendering the comment irrelevant. Loving something =/= being good at something. Snyder himself might be a great example of that when it comes to his CB movies.
To me it's no different than a hockey fan who knows the sport inside and out saying "If I had all the gear, the right amount of practice, equipment, and knew how to ice skate I could totally make it to the NHL." Like yeah, that's a nice thought and all, nothing wrong with believing in yourself... but if you say that with no intention to actually get off your butt and make something of yourself, it's a completely hollow comment IMO.
I'm not trying to start something with you KS, I don't even like MOS that much, but that line of thought has always bugged me in general, and to me it's clearly coming from a place of not realizing how challenging it is to even write a mediocre screenplay, or heck even finishing a bad one. If the fans on this forum are going to be the next great screenwriters they shouldn't be saying "if this, if that", they should be busting their asses to break into the industry. It's certainly not impossible if you're dedicated enough. The training is nothing, the will is everything...and so on. So basically I think it's an utterly pointless comment.
Do I like what Snyder and Goyer (and Nolan) did with Man of Steel? Eh...not a ton. But I do respect it. It could've easily been a lot worse, and I personally think Superman IS a pretty challenging character to pull off.
