The Stand

The flashbacks and flash forwards do not work. The story loses all of its tension because we know in advance if a character lives or dies.

They play around with the ages, sex, etc of who the characters are in the original novel. That's okay...not great, but okay. For some reason, scriptwriters fell they have to do this to make their story their own. That's crap, but if they feel they need to do that (to make it more modern), I can live with that.

Improve it now. Do what they did with Godfather 1 & 2, issue a version that is linear. You'll have a much better story and a better mini-series. Sometimes going basic ( i.e. Straight story time ) is the best (dramatically) way to go.
