Only one thing
I didn't believe Hugh Jackman as religiously motivated. He mentions church once and says "what in the name of God" a few times and in those situations it sounds forced. U don't think he needed to be religiously motivated to oppose artificial intelligence. They could have removed this plotline comfortably.
Other than that, I loved the movie! It was way better than I expected, and I think it was much better than Elysium. This movie actually had heart and soul.
