If you went through the 26 years of Doctor Who, the longest running sci-fi show in history and you needed to pick the top 5 or maybe even the top 3 adventures, I feel comfortable saying that 99% of the fans would easily place The Talons of Weng-Chiang" in that group. The show comes from the pen of Robert Holmes and was the final show under the helm of producer Phillip Hinchcliffe, who had produced the greatest group of adventures ever for the Doctor. This, combined with the most popular Doctor of them all, Tom Baker and a wildly popular companion, Leela, makes for a grand adventure.
Taking place in Victorian London, this is one of the richest adventures in the history of the show and one of the most well written with some fantastic characterization. Magnus Greel and the Homonculous creature as well as Li Sen Chang are magnificent villains in this thriller. Yes, the giant rat is cheesy but it's all part of the fun of '70's Doctor Who. I can't recommend the adventure highly enough and there are a lot of great extras as well. I think it's also a great homage to Robert Holmes that, of the Who adventures that are out on DVD or are about to come out, there are quite a few Holmes stories amongst the few out so far, including "Carnival of Monsters", "Spearhead from Space", "The Power of Kroll", "The Ribos Operation", "The Ark in Space", "The Two Doctors", "The Talons of Weng Chiang" and "The Caves of Andozani". So, in essence, of the 158 adventures in 26 years, so far, 23 have come out on DVD. Of those 23, 8 have been written by Robert Holmes! And I believe Pyramids of Mars is coming out next, also from Holmes. Can there be any doubt that this man has done some of if not THE best "Who"?
