The Triangle Era is really great, but if you can... I would start with Byrne's "Man Of Steel" and work forward chronologically. That way all the past references make the most sense, especially as the stories start using those pieces as things move forward. And yeah, I love the Louise Simonson video too, you're very welcome. And I appreciate that!
By mid-western ethic, I mean more about his mindset. Not that it only comes from there, but in the U.S. it's generally (or at one time was generally) seen as a midwest thing; the almost farmer-like ethic of "roll up your sleeves and get the job done" kinda thing. The Norman Rockwell part only because his childhood wasn't dark, brooding - but something largely positive, which Richard Donner saw as something akin to a Norman Rockwell painting. There's a simplicity to it, especially in a comics world where it seems like the only way a "good person"/hero is forged is through pain. I like this idea of a happier fighter - someone who can bear down when he needs to, but generally takes most things in stride and handles them well.
You're from India? That's fantastic! I love meeting fellow fans from all over the world. I'm from Iowa, in the US, myself. Not too far of a drive from Kansas, actually. A very cool, fascinating perspective on parents and culture, too. There's a lot of truth in it, too - both the happy and the sad. Progress is generally a wonderful thing overall, but it certainly does - or at least can - come with some unfortunate consequences.
Totally agreed on the sweetness of him remembering his mother, both as Clark and with the costume. And yes, every other hero's costume has been influenced by his - one of the reasons the iconic/classic ones always jump out more at me than the newer. Of course, I'm 37, so that's got something to do with it, too.
And my apologies for not clarifying on IL! That's the state of Illinois, where the "official" Metropolis is in the U.S. (bills itself as "the home of Superman"). Not a big town, only about 7,000 people.. but they have a Superman museum, a great 15ft tall statue of Superman and and smaller bronze one of Noel Neil, the first Lois Lane - and each year they have a Superman Celebration on the second weekend in June. (
www.supermancelebration.net if you've an interest). The pic in my avatar is me at the Celebration, actually (in a suit my mother & grandmother made back in '95 that fits better now than it did then!). Fans from all over the world come to it, especially on a big year like next year (Superman's 80th anniversary and the Celebration's 40th year). If you ever have the opportunity, I highly recommend it.
Hope that helps!
