I can compare the anti climactic ending to....
I enjoyed the verisimilitude of the experience. I empathized with all the characters. The performances are brilliant. My one gripe is the anti climactic ending. I was emotionally invested in the story. I went along on the arduous journey because I was concerned for the professor and the prostitute. The anti climactic resolution ruined the movie. All the events leading to the resolution were pointless. It's like getting seduced by a scandily clad woman, getting invited to her place at night, only to discover her lying asleep in bed just like the hooker. What a disappointment.
