There's a lot about this movie to like: the John Williams score, Olivier's turn as Van Helsing, Donald Pleasance as Dr. Seward. But Langella makes an awful Dracula, IMO. This version is worse in the goofy-romance dept. than Coppola's.
I need to at least rent this sometime, though; haven't seen it since it first came out.
This thread prompted me to Netflix its subject, as I'd been meaning to check it out for years. Disco lasers and Harlequin romance-novel elements aside, it's actually a pretty good little film. It's kind of a big melting pot for cool ideas from various prior Dracula adaptations...there are lots of nods to Lugosi and the Hammers, although Langella's performance is unique. Another thing I liked was how it upholds a lot of the traditional vampire mythos, but doesn't make a big deal out of it. Olivier was also a terrific choice as a frail Van Helsing with a will of iron. Not exactly Peter Cushing, but well-played.
Although it definitely stood out as revisionist tinkering (in that no film I can think of from the 70s has a desaturated look like that), I grew to rather like the blanched colors. And that John Williams score is terrific!
