The Marian Conspiracy feels like a classic Pure Historical adventure. While the plot isn't that complicate, it does provide a compelling story that will make the running time fly by. After all the intrigue, by the end of the story I was satisfied, if not a little sad for PLOT reasons. At first I wasn't sold on new companion Evelyn Smythe, her bossy and grating personality was a turn-off, but by the end of the story I was sold on her. Her temperament is a great match for the Sixth Doctor. The rest of the guest cast did an excellent job, with some of them being recurring names. Overall, this was a great flashback to early Doctor Who story telling.
