I thought it was okay. I didn't love it.
I thought I read or heard Alain Guiraudie (Stranger by the Lake) make some comment that suggested he felt some skepticism about a straight man helming a film about lesbians. Darn, I haven't found the source of that. (My apologies, Mr. Guiraudie, if I'm misattributing that to you). I share (or independently feel, if I'm mistaken) that skepticism.
I didn't particularly love the storyline. Maybe I just don't relate well to lesbian melodrama. Like I said, I thought it was okay. But I did also get the feeling that it was to some extent the fantasy of a straight guy. And straight guys, I think, are well known for their interest in girl-on-girl action. Of course that's the feeling I got about the love scenes in particular. That is, here is a straight guy's take on what he hopes lesbian sex is like: hot chicks going at it in ways that conform nicely to heterosexual male fantasies. Really, eye candy for straight guys. Not only the love scenes. The casting itself, I suspect.
I am not at all saying that there's anything wrong with that. Either straight guys telling stories about gay women or lesbian sex scenes that are staged, really, to turn hetero males on. I'm only saying that I thought it undermined the verisimilitude of the film, which in turn didn't help me to like it better.
On the other hand, based on the anecdotal evidence in the video below, the lesbians featured don't seem to have any particular problem with the loves scenes in BitWC. They do seem to express some skepticism, which might to some extent validate my own skepticism.
Then again, one of the women says something like she loves the rest of the story. So I guess the rest of the film really spoke to her. Perhaps that's the only stamp of authenticity the film needs...
..."dubious" love scenes notwithstanding.
