Totally miscast - Emilia Fox is too confident, beautiful and elegant to play the plain, awkward, painfully shy second Mrs De Winter. Charles Dance is too old to play Max De Winter (he's supposed to be 15 - 20 years older then her, not 30) and he lacks any sense of darkness or anger. Even Manderley itself is dreadfully unimpressive. Only Diana Rigg, as Mrs Danvers comes anywhere near creating a character similar to the book.
The directing is of the 'point and shoot' variety, with no subtleties.The one trick, with Mrs Danvers and the light, is lifted straight from Hitchcock.
In fact the whole thing has no sense of mystery or doom or tragedy. There is no chemistry between the leads, despite the script showing them kissing passionately at a time in the book when he barely touches her. There's no romance between them, in fact their kisses seem awkward and forced, and a bit disgusting, given how much older than her he looks (not to mention his lack of sex appeal and passion) The script itself is terrible, deviating from the book, having her challenging him at a time when in the book, she can barely speak to him.
If you love the book, like I do, don't bother with this. Watch the Hitchcock version, with its great acting, sense of tragedy and doom, deep romance and a script practically lifted from the book, instead.
