It's an old Merchant-Ivory period piece. Pleasant enough, but kind of stilted in places. In part. some of that may be deliberate, to reflect the buttoned-up nature of the times, but it's hard to say.
Amusingly, the image that's shown as I type this on Letterboxd — which may or may not be the image that accompanies the post when it reaches my blog — is from the very last scene of the film, if I'm not mistaken. An odd choice.
