I saw it Friday night, pretty damn good movie, especially since it was a heist movie (we've had plenty of those recently) but with an original idea. (See what I did there?
)
The only thing that bugged me is that there was no moral questioning of what they were doing. They were more or less freely going into other people's dreams and had no second thoughts about it, but they knew it was bad and had nothing against it. Even the younger girl who got brought into it didn't even question their motives.
There's no way you can say it did or did not stop spinning. We will never know and that's what it so badass about it.
