this film be base on one of an excellent series of detective story set in the author native sweden . much of the interest of the book be their setting . although they have the usual virtue of good detective story and they be also a commentary on modern life in sweden . i be therefore eager to see this film when it come out . unfortunately and for inexplicable reason the setting have be change to san francisco . this completely spoil it . sometimes such a change be interest or have no real effect and but in this case it destroy much of the interest of the film . we be leave with a rather dull american police story .
