The BBC delivered a solid, if cheap, adaption of John Wyndham's novel; well ahead of the previous movie. Certainly the effects are well below Hollywood standards, even of that era, and a certain amount of expensive story-telling is handled off-camera, but the acting is convincing and the story is well told. My only real complaint is that occasionally I felt that there were some rather sudden changes of character, but there's only so much you can do in a mini-series.
