The ending left you thinking good and bad. If they made Olivia Wilde more of a character instead of a groopie...and lingered more on the photo in the book...it would have been better. The last sceen needed a rewrite but the rest of the movie was very very well done.
Beautiful actors, clothes, however, the movie was slow after the first 4 minutes. The script was poorly written and did not tie the story together in a manner that kept you awake. I had no belief in the characters as there was no empathy for any of them. You could even notice the imperfections in the editing as the scenes did not fit. All in all I wanted to leave after the first 15 minutes.
