Um. Wow.
Even if you're not counting down the minutes until Watchmen comes out, if you are of a certain age, this is pretty much a perfect recreation of the time it's supposed to be, well, recreating. My nostalgia centers are currently well above the flood stage, and it's not just because of the production quality. I'm not 100% sure, but I believe the dialog is taken almost directly from the book I loved and read over and over as a teenager, but I don't have time to take mine out and fact check at the moment.
Still. Wow.
