It is impossible to review this film without comparing it to Alfred Hitchcock's 1940 version. This production has no romance, no mystery, no suspense, and no atmosphere -- all of the things that made Hitchcock's version a masterpiece.
The only thing that makes this film watchable is Diana Rigg's new take on the character Mrs. Danvers. I found her to be the only believable character in the production -- different than Judith Anderson's interpretation nonetheless, but well done.
If you've never seen a film version of Rebecca, watch the Hitchcock version instead of this one.
