Honestly....while there's a few iconic moments- like the guy running the wheel; I felt that it did a very poor job of communicating what the book does.
though, also, I might be a little biased to the greatest SciFi film to date being the 1950's version of The Day The Earth Stood Still. sure, it's not got the action. it doesn't have apes beating apes. But it does have thought provoking content that is still poignantly relevant to today's world. (it's a criticism of Mutually Assured Destruction,)
