Here's the problem with Red Dawn versus the remake.
In the original Red Dawn, all of the protagonists are just ordinary Americans who become partisans.
In the remake, notice how they are led by a Marine who has come home and the father is a police officer.
In other words, modern Hollywood cannot wrap its head around the thought of "ordinary" people becoming heroes. Our new heroes have to be government trained.
Whatever happened to the Campbellian Journey?
