This BBC version of My Cousin Rachel is part of numerous versions of the Daphne du Maurier novel. Though I have read the 1948 version starring Richard Burton and Olivia de Haviland is the best.
This version is not perfect, but it is good. However, the first episode drags. The second part of the second episode is rather droll. Once, Cousin Rachel (Geraldine Chaplin) appears the storyline gets moving. The third episode is the best. The fourth episode there an illness induce delusion that is too long.
Christopher Guard who plays Philip Ashley, talked in a loud voice for most of the time and his acting style was tiresome and annoying.
I do commend Chaplin's performance. She played Rachel as I remember her in the book. Rachel was an enigma. Was she really an innocent woman who is misunderstood and mistreated by men or a cold and calculating shrew?
Overall, there are dull moments, some scenes with Philip lasted longer than it should and a great performance by Chaplin.
I found this version on the Internet Archives.
I recommend the book.
