Whether or not you deem it a realistic scenario does not detract from the artistic quality of it. What about 1984? Brave New World? Dr. Strangelove? All of them gloomy and dystopian, and all of them damned good!

Nuclear warfare was (and still is) a very serious threat. Just because we've been lucky enough to skirt such a conflict doesn't mean it's not a viable threat. And depending on who you ask, ecological collapse is a very serious issue as well. I like these types of stories because they serve as a grim reminder of what could be. And maybe, just maybe, they effect enough change to steer us clear from it.
