the point is the idea didn't start of as the fortress of solitude. That was stolen from Doc Savage, name location and everything. The idea however of a secrect location that he used to get away from it all and keep relics was very much alive in the Secret Cidal. The idea was there they just changed the name and location to cash in on Doc Savage. No point in arguing it. If BAtman had a cave where he did his crime fighting but it didn't happen to be officially named the "Batcave" pretty sure it was the same location concept and all.
I'm not even sure why you're making that point, to be honest. I'm not arguing that the Secret Citadel isn't a similar idea. But the Secret Citadel is not The Fortress of Solitude. It is not located in the Arctic, as the Fortress was.
You emphasize the idea that he builds this impressive fortress to just...get away. That is something he could do anywhere. Yes flying off atop a lofty mountain would serve that sole purpose just fine.
Based on what? This is a man with superhearing. How is just flying to the top of a mountain going to do anything? Hell, in JJ Abrams SUPERMAN script, Superman flies to the top of a mountain to be able to hear people with his superhearing better.
I suppose he COULD fly to the top of a mountain, or to wherever else, but the mythology has this place...it's called The Fortress of Solitude. It's Superman's choice not to go flying around to mountains when he needs rest and meditation. So I prefer to honor that mythology, rather than make up reasons why he wouldn't need that and could go sit on a mountain. I don't really think it needs to be justified outside the fact that this is what the character himself decides is needed.
However if he wants a place to go to learn about his heritage, keep relics of his adventures, and do more than sit around watching tv then yeah, a huge secret fortress makes sense. Yes it is a location for his personal pursuits, a location of solitude. But if he's just there to chill, sit around and do nothing then no it's not really needed. In the comics it's always had some function.
No one is advocating he do nothing but "chill" there all the time.
Being a place of rest and meditation IS a function.
I have said very clearly that it should eventually have other elements than just a place of solitude.
But it doesn't need to start out as Superman's Batcave. It should start out as a place of solitude, perhaps with the idea that it can become more. And then, when he's comfortable with who he is and what he's doing, he can expand it, if he wants to bring work home, or add touches of Krypton.
THe Fortress first appeared on the show when he removed the sphere from Brianiacs ship, he needed a place to store it so he brought to a location he liked in the arctic. I believe he said something about he knew he'd find a use for this place or it's potential etc. Later he adds the animals from the Collectors ship. So yes it is a place for solitude, he "me" time but he didn't just decide go find a random place to get away, it had a function in the show.
Apparently, the function was to be a storage locker for a sphere that contained information about Krypton. A sphere he could have kept in his closet.
Sue me if I don't find that concept half as compelling as...a place to rest and meditate AND keep a sphere with information about Krypton.
So the show decided the Fortress should be used for storage VS solitude.
How does that have any bearing on my statements about what it should be in a film?
