IDK. I got distracted by trying to figure out what the particular type of apocalypse was in The Road. I haven't seen it advertised much, it seems to have been bumped by The Road and the ads for what I heard was the sucktacular Paranormal Activity.
The best postapocalyptic movie would be the big screen version of The Stand (miniseries was OK but could have been much better).
The only non-lame thing about the 2000 fervor was Millennium, the series with Lance Henriksen.
If I was some movie bigwig I'd do the stand, but trim some stuff, books are longer than movies. The series included too many minor events.
