Grand Assault's review is spot on in this case. I too wanted this movie to be so much more, and was fascinated by the trippy animation, but overrall it was a dissapointment. This film had a great theme and animation, and the 'concept' of the plot was decent, but through most of the movie, the dialogue was just too distracting and off-topic that I just got lost and stopped caring about what happens to any of the characters.
And i think Keanu once again proves that he's just a hack of an actor. The only good performance in this film was from Downey Jr, as well as a few scenes from Harrelson.
