For those who didn't get it...
Remember the Terminator? The paradox? The terminator is sent back to the past to kill John Connor in utero, but his coming into the past is the very thing that brings John Connor into existence?
This movie is a little like that.
A man loses his wife in a car accident, his daughter is taken away from him by the courts, so he drowns himself in his work, alcohol, and drugs to cope. When Emma has a seizure and ends up in a comma, he is torn between going to the important meeting or going to the hospital. He chooses the meeting. Emma dies. Wrecked with guilt, John commits suicide. He becomes Ink, roams the dreamworld, forgets who he is, and eventually comes to believe that becoming an Incubus is the answer. He travels TO THE PAST, BEFORE Emma's or his own death, and snatches Emma into the dreamworld, sending her body into a comma. Now, I'm not sure why it had to be Emma he brought before the Assembly, but my guess is, it's a bit of the reversed Biblical Abraham thing: the Incubi want proof of his intention to become evil, and what a better test than to have him sacrifice his own child?
However, the Pathfinder changes the past by causing a chain reaction of little accidents that lead to John being in a car crash. Thus John never goes to the meeting, his daughter never dies, and he never kills himself as a result. Instead, he's brought to the hospital, finds Emma, and realizes she's more important than anything. Simultaneously, in the dreamworld Ink realizes who he is and what he's about to do, and fights the Incubi to save Emma.
Emma never dies, John never commits suicide. Happy end.
The only two things I'm not sure about is, what happens to Ink after the end (does he just disappear because the past has been altered?), and who Liev really was.
Other than that, it was a neat little movie. I wouldn't call it that mindblowing or original or amazing, though. 3,5 out of 5 stars for me.
