This really was a thoroughly crap film back in the day and though it hasn’t improved with age, I guess it was onto something (well at least the novel on which it was based). Here is Joe Dante making a case for the film to be reassessed, at least on the grounds of its prescience. Here too is Vincent Canby’s original review in the NYT.
[w]hen no place on earth can hide from spy satellites, when backward, oil-rich nations control Western economies, when the United States President is crooked and inept, when atomic bombs can be bought on the open market if one has the cash and when the citizens of the world watch themselves on the nightly news as if they were actors in a nonstop television spectacular.
