I really loved the first 1/3 of this movie, but it eventually fails. The performances are great but I thought it was eventually crushed under the weight of the "seriousness" it was trying to achieve. It simply goes on for too long, and feels extremely out of its own depth. The obsession with food (preparing, sharing, eating), violence, and sex just comes off as...sophomore year of film school.
All that said, I will admit that I loved the (tiny bit cheesy) 70's international locations, the overall historical intrigue, and the "Papa" character.
