Now if you have watched Kill Bill, you would know what a stylish director Quentin Tarantino is. But the real strength of his movies is the depth in the script and the performance that he extracts from the cast.
Inglourious Basterds is certainly a must watch. Don't be deterred by the fact that it is another movie about World War 2 and that it is as much French and German as it is English, it makes a great watch.
The movie is about two parallel plots being hatched by disconnect groups to assassinate Hitler. While one is hatched by a French Jewish girl whose family is executed by Germans, the other is led by a team of Jewish Allied soldiers. Incidentally, both plan to assassinate Hitler and important German officers during the premier of a German movie at the theater owned by girl.
I personally loved the movie because of Christoph Waltz. He plays the role of SS Colonel Hans Landa who also was responsible for the death of the girl's family. Waltz excels as a The Jew Hunter. While one can easily hate the person, it is an actors nightmare, as Tarantino himself has acknowledged. As mentioned in Wikipedia, "...character who is courteous and speaks four languages but is self serving, cunning and callous, Tarantino feared he "might have written a part that was un-playable".
No wonder, Christoph Waltz won the Oscars in the Best Supporting Actor's category. Very nice!
