Good Movie / Stupid Movie: Both?
Reading most of the message board comments, as well as the reviews, it seems that most hate the movie, but some love it. There are very few in the middle.
It is from a book, so any plot points that seem stupid are attributable to that.
One significant theme in many comments is the feminist / lesbian undertone. I guess it is there is you want it to be, but (and I am a guy) I think that if the actresses, and the director, were not known for their sexual orientation as well as devotion to "feminist" film making (whatever that is), then it wouldn't even be an issue. Perhaps only insecure men raise the topic. And maybe it is because of a few stupid moves the characters make (men included, by the way).
See this movie is you want a family drama set in a post-electricity World. It delivers an entertaining story, and for the most part a plausible one. The acting, directing, and entire production are very good.
