I just finished "The Mind of Evil," "The Claws of Axos," & "The Daemons." I think they're both really fun UNIT stories. I love the way they were developing the characters of Captain Yates & Sgt. Benton and their relationship with each other. Plus, lots of fun motorcycle chases.
I was a bit annoyed with Stephen Thorne's portrayal of the head Daemon. While I love his rendition of Omega in "The Three Doctors," I think he needed to tone down the screaming a bit in "The Daemons."
