It's quite a bizarre piece of advocacy - in heaven a man comes to his senses when he realizes that his wife was his only true love (despite many other attempts by him to court others), and they sort of live happily ever after. Although smart in execution I feel that this premise makes for a rather one sided view of things. And the longer I think about it, the more depressing it actually gets. It's not so much the anti-morality I object, but simply that it's not funny enough. Quite possibly it is sort of a WW2 Vegas-weekend movie version, and the undertones simply don't work anymore these days.
Other than that, this is Technicolor at its fullest glory (especially RED) and quite an amazing picture to watch. But maybe expectation for this Lubitsch were light years, so I could have only come out disappointed. Still looking forward to Trouble in Paradise, though.
