A Matter of Life and Death (1946) review

A British pilot (David Niven) whose plane - and crew - were blown apart somehow evades death (blame the fog!) but Heaven - realizing a miscount - chases after him. The fantasy elements are excellent - Earth is Technicolor, Heaven looks like it was shot by Sven Nykvist - but the story elements are left wanting: the final court trial turns strangely into a U.S. versus U.K. confrontation (apparently the film was created as propaganda to smooth ties between the two powers), the 'love story' that is supposed to exist between Niven and Kim Hunter doesn't have the necessary chemistry (though the script admittedly 'throws' them together) and most importantly, am I the only one a little disturbed by the fact that the ending virtually negates the rest of the movie, turning Heaven into a neurological abnormality? It's admirable for trying to tackle the concept of love and death in wartime, but I'd rather have Here Comes Mr. Jordan for my Post-Life Narrative. Sorry.
