I think that what perhaps makes the original story problematic though is that, by concentrating on the characters in the apocalyptic future, it focuses on the characters who are basically doomed and at a dead end story-wise. If it skipped the whole time travel aspect and if it was just a story about the characters' fight against the Sentinels in a dark apocalyptic world, it would be one thing. But because it introduces time travel and hinges the outcome of the story on the actions in the past, it also robs the characters in the future of any real chance to prevail in their fight. It doesn't make it a bad story, but perhaps unpalatable for a major summer blockbuster. Audiences can deal with deaths and sacrifices that achieve something, but futile deaths and actions that achieve nothing wouldn't go down so well IMO.
