Take This Waltz is most successful if viewed as an accurate (yet flawed) character study of a depressed girl in the ass-end of her 20's. I think the word girl could even be replaced with person. Men go through similar phases in their lives but, writer/ director Sarah Polley concentrates only on Margot (Michelle Williams).
My opinion on interviews is widely known. I enjoy doing them occasionally, but am not the biggest fan of all the work that goes into preparing for them. Often, you have to talk to a publicist and the back and forth starts, trying to find a time that works for everyone involved.
