Horrendous!
Just saw the movie and my God, I haven't seen such a terrible movie in a long, long time!
What works in litterature doesn't work in cinema, and this is why this movie fails horribly. 2 hours of CONSTANT dialogue. Insipid dialogue that is, with characters answering questions with questions etc. While wordy philosophical considerations are good in a book because you have time to drop the book and think about it, they really don't work in a movie, AT ALL.
Seeing this movie was like seeing the architect speach in the matrix reloaded only it lasted the whole movie, and it was even worse!
Keep your dollars, save your brain, don't see this movie!
