The movie starts with one of the best single scenes I have ever seen., the Nazi colonel, Hans Landa , visits a French farmer suspected of hiding Jews. The tension it builds up is absolutely incredible, not only because of Tarantino's once again brilliant script(a large portion of which is in a foreign language) but also because of Christoph Waltz's amazing performance( for which he won an Oscar) in his portrayal of Hans Landa, an evil, charming and supremely intelligent Nazi colonel.
Brad Pitt also delivers, in my opinion a strong performance, as Lt Aldo Raine, as with many characters in the movie such as Goebbels and Hitler he is a comedic character.(Yes, Hitler is a funny character)
The rest of the English Basterds unfortunately have somewhat weak acting imo.
Melanie Laurent plays the Jewish woman, she is the proprietor of a movie-house and through a nazi war hero love-interest she lands a film premier which Hitler attends.
She is the "heart" of the movie without which it would be too cold and gruesome.
A large portion of the movie is in German, French and a little Italian played by a European cast unfamiliar to Hollywood, and they really shine.
The plot is a bit fantastical but a great story nonetheless.
For this gruesome, evil and funny story I give 8.5/10
