The Mind of Evil - Episode 5

OK, that was a lame cliffhanger resolution. The Doctor and Jo are attacked by the Keller Machine... which then leaves. Wow. Interesting to see the Doctor and the Master working together on a "science project", so to speak. I love the Master's "Yep" reply when the Doctor tells him to grab a coil or some such. And we get a patented Third Doctor Moment of Charm (as coined by Doctor Who Magazine's Time Team during their marathon), with the Doctor telling Jo about being locked in the Tower of London with Sir Walter Raleigh. Nifty music as the Brigadier approaches Stangmoor Prison, and also another nifty bit of music during the attack inside. And a decent cliffhanger, as Mailer (who's a very good villain) points a gun at the Doctor, and a shot rings out...
