This may not be the ideal moment in history to release a movie like Heaven, in which we're asked to sympathize with a woman who stashes a timed explosive in an Italian office building and ends up detonating four innocents. The righteous bomber is played by Cate Blanchett, about whom the film seems to be asking, ''Could you really hate a terrorist this luminous?''
She never meant to kill those people, you see; the bomb was intended for an executive drug dealer. (As if that excuses her.) Confessing to the crime, Blanchett then escapes with the aid of a young police translator (Giovanni Ribisi) who's in love with her. Based on a script by the late Krzysztof Kieslowski, ''Heaven'' is further sad evidence that Tom Tykwer, director of the resonant and sense-spinning ''Run Lola Run,'' has turned out to be a one-trick pony -- a maker of softheaded metaphysical claptrap. It's enough to make you want to see him run again.
