Insights Into Douglas Sirk
I love this movie -- no apologies, and found nothing comedic about it. Perhaps there's a bit of irony here and there, but growing up in the 50's, it's much easier for me to understand the social attitudes expressed in the film, as well as how the film was made itself.
I found this site which gives great insights into the work of Douglas Sirk, including discussions on his films, including this one.
