Operation Petticoat

This movie is a wonderful example of a film that isn't particularly deep or important BUT that still works well because it's so much fun and the writing, though quirky, works. Of course I will admit that the plot from time to time gets really silly (culminating with the sub being painted pink and being forced to go that way into action). I guess it's just that this is a nice blend of acting by Cary Grant and Tony Curtis in a cute little war picture that ALMOST makes WWII look kind of fun. The end result is charming and silly and worth watching but with no real meaning or significance at all--and is that always such a bad thing?
