So: Inception
SPOILERS! (Click to view)It was excellent. If the movie had nothing else going for it, the scenes of training Ariadne, and all the tricks she pulls on her imaginary Paris would have been worth the price of admission. And happily it has much more than that.
But there was a twist I was expecting in the end, and one I came to be much more charmed by than the actual closing twist. I had imagined it this way:
Ariadne and Fischer turned out to be Cobb's daughter and son, and the whole job was a deliberate play from the start to incept into Cobb the healing he needed to get over Moll. Cobb was the one being set up, not Fischer. Ariadne had inherited her father's gift for architecture. The need to protect Fischer throughout the job was a ploy to get Cobb to emotionally attach to him, and choose his own son over Moll.
Given how open the ending left the movie, this could still be true.
