Did the director leave 3/4 the way into this movie?

Rating: 6/10 (2 April 2009)

I, like many people, saw the trailers and read the blogs about the concept and story behind this movie. In a nutshell, I can sum up the writer's intent: the universe is cruel and doesn't give a rat's posterior about you.
Moving onward, Cage was no the best guy to play the main character and the backstories could have been fleshed out a bit more. Too much focus is placed on the "numbers" and Cage's character should be MUCH more skeptical of the numbers since he's this brilliant scientist professor.
But I must admit that although the story kept me interested enough to see it through the whole way, the last 15 minutes of the film...did the director walk off the job and they put some shlub in there to finish up the rest? I did not like the ending but I am glad that some directors out there don't always end their movies on a happy note. I think it's supposed to leave you with something to think about as you walk out the door but it fell short for me.
Good concept for a movie but the execution wasn't so great.
