Fun, Underrated WWII Romance
I can see why this kind of movie would annoy the pants off certain kinds of filmgoers, cynics in particular. For one thing, it's hard to categorize, which would be the first thing to throw off would-be critics. Despite the film's premise, it's not really a chick flick, but because the filmmakers don't make a big deal out of the battle scenes either, it's not really a war movie. The "romance" in HS is sincere, but even that isn't treated too seriously either. In fact, I can imagine plenty of people not liking this one because the whole thing feels calculatedly ironic.
All this could be dismissed as proof that the film lacks a consistent tone; I think the movie is simply a forerunner of romantic action pictures more common in the 80s, like Romancing the Stone and High Road to China -- or Raiders of the Lost Ark. (It's fun to see Ford transitioning from Han Solo to Indiana Jones.) It's a pastiche-y genre in which nostalgia, romance, light satire, and violence have to achieve just the right balance.
There, daddy, do I get a gold star?
