This is a lovely adaptation of one of the lesser-known Jane Austen novels. It's a slight story, a satire on the effect on impressionable young girls of reading overblown novels but also a very charming love story. I would highly recommend it. It's beautiful to look at and the leads, Felicity Jones and JJ Feild, are both wonderful in their roles, with a good on-screen chemisty, with an excellent supporting cast. They are all given something to work with and take the chance very well.
I love the light-hearted scenes of dancing and flirtation. The undercurrent of danger in this louche city of Bath are signalled but not overdone, the villains are fleshed out and believable, the scenes when Catherine thinks she has lost Henry forever, the quiet moments between Catherine and Henry and his sister, all wonderfully done.
I am not an unconditional fan of Andrew Davies' adaptations of classic novels as I think he sometimes goes too far in his efforts to bring out what he regards as the hidden sexuality in the books but in this adaptation I think he got it exactly right in giving day and night dreams to Catherine with her over-wrought imagination.
As others have mentioned, this is a small screen production and has to be seen in that light but it's a little gem. Highly recommended.
