I was a big John Wyndham fan after a teacher at my high school introduced me to his works. She learnt I was a big science fiction fan after a school project and suggested I read the book the Chrysalids (which deserves to be mad into a show too), after that I was hooked.
I then read the more popular Triffids which led to seeing the awful movie. Not too long after the BBC show started and I was happy too see something that stayed roughly too the book. The acting was pretty good, the triffids whilst not matching my vision of them where pretty darn good for the day (I'd love a remake with CGI triffids someday).
Recently watched the show again and still enjoyed it. Stands up pretty well even today.
