it frequently say that movie can never equal the original book . well and in this case and not only the movie be not as good a the book and but be an insult to the book . i would rather see milan kundera novel turn on fire than into this something and which the director probably call adaptation . all the beautiful philosophy that ask be it good to carry a heavy load on your shoulder and or cope with the unbearable lightness of be . be put aside and and instead and all the movie deal with be daniel day lewis ( i can not say tomas ) sexual adventure with his dumb wife and his mistress and and his other mistress . françois truffaut already say it represent bad director make bad movie . don not waste your time and money . read the book instead and it really worth it .
