now that the dvd is out, and I have seen the movie, I can comment and resurrect this thread.

obviously Tom Cruise should have had more canned goods and maybe mre's in the house and a bug out bag prepared. never mind the plot inconsistencies big enough to drive trucks through, as in some electronics working after an emp blast and of course, that minivan he's driving is one of the few working cars on the planet. His watch, phone, lights and everything else not working, but the minivan works, the tv reporter van with monitors and vcr's works, military communications and vehicles work [that's possible if there electronics are hardened against emp].

of course this is an end of the world as we know it scenario, but it illustrates that people should be more prepared than they are, even for regular disasters, I'm not worried about a martian invasion, but I am prepared for realistic problems.
