I'd never seen this topic before, but I'm contributing to it now. I watched the Christmas episode from this series, "The Case of the Christmas Pudding" last night because it was on a DVD my parents have of Christmas episodes of various old TV shows from the 50s and 60s, including this 50s Sherlock Holmes series. I thought it was pretty good for a 26-minute episode. At the beginning, I wasn't sure it was the most inspired, but it ended up kind of fun and exciting. I thought Howard Marion-Crawford did a good job as Dr. Watson getting a little bit incredulous at Sherlock for keeping out of the loop when he could have helped, which he ends up doing anyway. I don't know how easy the show is to track down, but that episode was good Sherlockian Christmas fun.

Oh, that's cool! I might check some of the others out when I have the time.
