This movie was a true chore to watch. I don't know why it is seen by some as an artistic film--unless "artistic" means painfully dull and uninteresting.
The entire plot is about two uninteresting people having dinner. The less annoying one (Wallace Shawn) is in awe of how brilliant Andre is, while I felt that Andre was mostly full of crap. Andre was a pseudo-intellectual character that delights in his own importance. If I had wanted to see such an obnoxious and self-important people, I would have watched an episode of Frasier--at least he and Niles are funny as well.
My advice to Andre is STOP talking. Please for the love of God, stop talking!
