That's an example of exactly how the '50s theme should be used. The problem is that Bethesda didn't stop there, and had people living in suburban-looking homes in '50s garb acting like they had any idea of what the pre-war world was like. IMO the '50s theme should be used for contrast, not to depict the post-war world. They got some of it right in FO3, but they went too far, IMO.
I personally think the post-war world should be all Mad Max, filth, danger, and atrocity, so that when you run across references to the pre-war world you think, "Wow, the world must have been perfect before the war, huh (even though it wasn't)? Look at what we've become. Look at what we've lost." It's the contrast that makes it effective. I think they ruined it by shoving it down your throat at every turn. Then again, I've always favored subtlety in fiction over heavy-handed "hey guys look at our neato literary device lawl!"
Well, the way I personally felt was that it wasn't shoved on us, it's just there were plenty of relics, I mean the only place you really saw Pre-War 'daily' styled clothes was in Tenpenny Tower, and the way I see it is that Fallout should always have some relation to the past, I mean, look at TPT and The Lucky 38, both were ideaisms of 'perfection and civility'. Maybe you noticed or maybe you havent, but Pre-War furniture and clothes and etc were easily affordable and common unappreciated items before the war, however, anything pre-war themed that is clean or well kept is usually found as a luxury. I.E. Tenpenny Tower and The Strip, both places where the rich and or powerful could take a sip from that slowly drying well. People like Tenpenny and House keep the feel of that world alive,albeit on a 10% or less scale as far was we see. The way I see it is that it is a literary device of 'what you may not appreciate now is considered a luxury to others.
