I saw it yesterday with 2 friends. They both hated it except for me. I thought it was brilliant and worth the nine dollars I spent on the ticket.
But something that was just silly was how long it was taking for the car to fall. I mean I know there is time distortion involved but really?
At first I didn't understand why it was taking so long, and then I remembered that that was also in a dream. So it made enough sense to me. Obviously it wasn't perfect, and I do agree that it seemed like it was taking much longer than it should have, but it's a movie, and movie's have flaws.
The ending was also kind of a disapointment as far as it goes as psychological, but it keeps you wondering.
How did your friends not like it?
