HERE explains it better than I could. But there are others that think along the same lines as me.
And with that said, it looks like Singer is making the leap to television this fall with "The Gifted," although (to be fair) Singer only directed the pilot. It's still exciting, and I've embedded the trailer below. I kind of wonder at this point if it will intersect with FX's Legion at all. I hope so, because Legion was really good. Another thing that's got me excited is that we'll see some sentinels, although they will look different from what has been seen before (Sentinels were the robots who raged war on mutants in X-Men: Days of Future Past). I just hope they aren't androids to save on budget. Androids are so the rage right now.
