Moria gives it a nice 4-star rating and says,
What most of the critics fail to credit is that the film is a powerful piece of storytelling. It marshals myth on a grand scale – the myth of the greatness of the American nation, the myth of the reluctant hero, the myth of the basic goodness of ordinary American people, and the myth of redemption and restoration of the country...SFGate says, "The dragging pace is one of several agonizing defects in this bloated sci-fi action drama" adding, "But to give Costner his due, the movie seems an earnest effort with noble intentions. And thanks to the grand scenery, it's consistently attractive visually." Roger Ebert calls it "good-hearted" and says,
parables like this require their makers to burn their bridges and leave common sense behind: Either they work ..., in which case everyone involved is a genius, or they don't--in which case you shouldn't blame them for trying.Rotten Tomatoes gives it a 9% score. Sad.
