Throughout this whole episode, I was unable to get beyond one major point that just kept rankling with me. The basis of the story is that the earth has been thrown out of orbit, and is slowly falling towards the sun, thus the temperature continues to rise, and people are evacuating north to try and avoid the searing temperatures that are occurring. It is even said that it is well above 40 degrees at midnight, with the sun still out. Well, if that is the case then the earth is also not turning on its axis. Which means that only half the globe is in full sun, and the other half must therefore be in full shade, and freezing to death! But that isn't even considered in the framework of the story. I mean, the earth isn't flat... is it?...
Beyond that, the problem that lies in the story is that it isn't really getting anywhere, and then we find that it is just a fever induced dream... except that in 'reality' the world is actually freezing, not burning up. Well, there's a kicker.
No doubt my afore-mentioned aversion to the planet spinning or not spinning harms my enjoyment of this episode, but none of it seems even remotely likely given the event actually occurred. A store with food still available and not trashed? A random guy using a gun to get water, and then leaving? Yeah, none of this really works for me.
Rating: Why not paint a sun shade? 2.5/5.
