The Gruntled family watched "Away We Go" last night, and enjoyed the whole thing. We saw it as a moral tale of two people who are deeply in love realizing that they need to get their lives in grownup order before their baby comes. He makes ridiculous jokes, she is indulgent and moves the family forward. He is delighted about the coming baby, and is sure they can work everything out. She worries in a perfectly plausible expectant-mother way. The core story seemed, to us, very familiar.
The shape of the movie is a road trip to see where they might want to live and to bring up their child. With both sets of parents out of the picture, and with flexible jobs, they can move anywhere. All the friends and relatives they spend time with are, of course, quirky (this is an indie movie). Each family has a different frailty of family life that is instructive to the central couple. The Gruntleds found the send-up of the New Age faculty family especially hilarious.
In the end, they come round right.
I then read the extensive comments on the IMDB message boards. I was surprised at the strong negative reactions of a whole strand of commentators. There are threads of sociology, too, as some people try to figure out what kind of people liked the movie, and what kind hated it. The main theory seemed to be that young hipsters would like it and others would not. I don't qualify as young or hip.
I think "Away We Go" appeals to people who like the moral quest to transform themselves to do right by a baby. The real appeal to me is that the central couple have a just sense of proportion about how big a challenge raising a baby is, and how wonderful.
