I liked this film; and had no concerns whatsoever about watching it, despite the relatively low financial return, which I don't understand and also, the relatively mediocre percentage on Rotten Tomatoes, which I also don't comprehend - the latter of which I generally check before watching a movie, the former to see whether it's an indie or not.
I guess that this genre is not for everyone; to me it's a Jane Austen with added intrigue or a sophisticated Dan Brown with less intrigue.
There is lots of innuendo and suggestion, which unfortunately is generally bluntly explained shortly thereafter; it would possibly have been more interesting to keep it more mysterious and therefore make the viewer think longer than a few seconds.
I enjoyed it overall and would recommend it to those of a literary bent, it's not a popcorn flick.
