This is one of our favorite movies at our house. Yes, it's dated, yes, the female role models are ridiculous, but in our house the kids are well aware that things aren't like that any more and that a woman's purpose in life isn't to find a man and get married. I did have to explain who Conrad Birdie was supposed to be (Elvis) and who Ed Sullivan was.. but the rest takes care of itself.
We talk about all that and just enjoy this campy, hillarious romp. The kids will be singing the songs for days to come -- it turned both of my kids (boy age 11 and girl age 8) into Musical buffs! We've now also seen How To Succeed in Business, Guys and Dolls, South Pacific, Oaklahoma, etc. I just trust their intelligence and we talk about how things were different back then and how far we've come as a society. Good, fun, entertainment for all!
