"Waltz with Bashir", directed by Ari Folman

One night at a bar, an old friend tells director Ari about a recurring nightmare in which he is chased by 26 vicious dogs. Every night, the same number of beasts. The two men conclude that there's a connection to their Israeli Army mission in the first Lebanon War of the early eighties. Ari is surprised that he can't remember a thing anymore about that period of his life. Intrigued by this riddle, he decides to meet and interview old friends and comrades around the world. He needs to discover the truth about that time and about himself. As Ari delves deeper and deeper into the mystery, his memory begins to creep up in surreal images. Written by intlpress@aol.com

My opinion: It's a very very good movie. I personally recommend it, whether you are interested in the middle east conflicts or not. Even though it's frame is based on Lebanon wars and massacre of Sabra and Chatilas' camp, it is an extraordinary legacy on youngster mistakes. Nothing is good in war.
