I had vivid memories of watching this show as a teenager when it was first shown on TV, and recently bought the DVD. It's not badly done, but at the same time I found it far less effective today than I did then. Surprisingly, the triffid effects didn't look too bad. OK, they're obviously fake plants, but they're about as convincing as could be expected on a BBC budget.
I think the main problem is that they tried to cram too much into a relatively short series, so the character development isn't terribly convincing. As some others have pointed out, a number of scenes are basically pure exposition with characters expounding their beliefs without much dramatic impact, characters meet and fall in love in a few minutes, and the whole 'should we help the blind or not?' issue is really skimmed over with people making up their minds very quickly: I know it would make rational sense to let most of the blind die rather than try to keep them alive, but I doubt that most people would write them off as quickly as the characters here do. Another issue watching it in the 21st century is that there are a few very 1970s haircuts that rather give away the age of the show :).
So it's worth a look, and it's a far better adaption of the book than the film from the 1960s, but there's still room for a better one!
