Tripods is an excellent adaptation of the John Christopher Books - The Tripods. If you are in your late 30's and remember this first time round then going back to it is heart warming indeed. Excellently cast and shot it shows the BBC at their best with great development of characters and storylines. But the reality is that not for the first time the BBC lets itself down again by not taking the story to its logical conclusion by axing the 3rd Series (Book 3 in the Trilogy)before it could be filmed. The BBC has done this recently too with the new version of 'Survivors' which was yet another high quality drama series that was sacrificed on the altar of reality television. It just shows you that this has been going on for years. So allthough SciFi fans will enjoy The Tripods the key decision you have to make when buying this DVD is if you are willing to buy a series that was only 2/3rds finished. I would say the answer is YES. Do what I did and go out and buy the 3rd book in the trilogy to take the story to its natural and logical conclusion.
