How are all of these people giving it 4 and 5 stars?
It was a confusing, poorly adapted turd in a bucket. The non-linear storyline degraded any chances for character development, they had little in the way of characters having discussions and more in the range of characters saying things at each other.
The vision of Vegas and Colorado were completely out of sync with the necessities of their novel. The world ends, there's less than 1% of the population, and you're trying to organize a *SCHOOL* and worrying about a 30-man police-watch force? Geesh, people, get your heads on.
And Vegas having 24/7 battle to the death matches and huge hedonistic displays when Flagg was scaling it up to become a military power? Flagg was against drug use and self-destructive behaviors (these were his pawns, keep in mind, he wanted them controlled and useful as tools against Boulder). The nature of Vegas completely undid that.
This production was so far outclassed by the currently out of date 1994 version that it was literally laughable. No dialog, only cool stances and glances and strangely timed dances.
