Awesome WWII movie, though a bit fictional

Rating: 9/10 (28 June 2017)

Most of the movie has some support from the history, except for, of course, how Hitler, Goering, Goebbels, and Bormann (the Gang of Four) ended their lives.
Christopher Waltz rules this movie, from beginning to end. His SS Colonel Hans Landa chills to my bones. I couldn't help thinking he is probably a mixture of Adolf Eichmann and Reinhard Gehlen.
What interested me is that (spoiler in the following): In the opening scene, Hans Landa compared German soldiers to hawks, while Jews to rats. He also claimed that what made him distinguished in the Jew-hunting business is that he could think as a Jew (thus easily found out where Jews would hide). This could be a revelation at what he would do eventually (at the end of the movie, Hans Landa rats against his own Führer). Also, could the last name of the SS Colonel, Landa, be a deviation from Lando in Star Wars Episode V: The Empire Strikes Back, who goes back and forth in between the rebels and the empire, for his own sake?
Everyone is this movie shines, except for Brad Pitt, who is the biggest disappointment for me. I would give the movie 10 out of 10 if not for him.
