Science Fiction is fiction based on scientific speculation. I REALLY want to call Jericho sci-fi, but it is hard to do that because it is (somewhat) plausible and rooted in actual science (Nuclear Devices are real - now if it was terrorist detonated cobalt devises that have the cities hit still contained within a blackhole like shround of darkness, then yeah sci-fi). However, super heroes, yeah... science fiction. Until you can show me the reality of a proliferation of widely varried and beneficial mutations spreading amongst the populace; superheroes remains science fiction in my book.
