It's considered polite to consider Borzage's post -war movies mediocre,which is completely unfair.Although they cannot match the director's 1927-1940 brilliant production (who can anyway?),some of them are acceptable,and some even highly commendable:such is the case of " I've always loved you" (1946) or "moonrise" (1948)."The Spanish main" (1945) although hailed by some as a pirates classic ,fails to excite ,perhaps because it is an impersonal movie.
"Magnificent doll" blends love stories with political subjects .David Niven ,cast against type ,plays the part of the villain,a politician who won't be satisfied till he owns everything .Ginger Rogers is good,but her character is a bit unbelievable.
In fact,at least to my eyes,only the first part is Borzagesque: Dolly's first husband is the good man we meet in many of his movies,the one ready to give it all ,to sacrifice everything,even his own happiness if the woman he loves is happy ;that was the story of the heroes/heroines of "street angel" "lucky star" "green light" "big city" ....
