I bought this adaptation at the same time as this Sense and Sensibility. Once you get past the 1970s fashion (and hairstyles) it is a great adaptation. It follows the plot of the novel closely – although some bits are left out (like little Charles’s accident and Anne missing the dinner party). There is a lot of ‘projecting to the back row’ acting (particularly by Sir Walter), but I think that is more about direction and the style of acting at the time – it feels like theater rather than a naturalistic film.
This isn’t a beautiful adaptation and it is certainly showing its age, but still worth watching if you love Persuasion and its quiet tone.
