The Curse of Peladon - Episode 2

Neat whodunit stuff in this episode, as the Doctor tries to discern who tried to kill them, then who tried to kill Arcturus. The use of the Ice Warriors as a red herring is great, wonderful to see a monster race used as nice guys. Again, good exterior shots, especially that bit of ledge that falls when Jo escapes from the Ice Warriors' quarters. We get some more glimpses of cute Aggedor. Alpha Centauri is a delightful alien. A unique design (thankfully adjusted before filming to make it less phallic), with a squeaky voice that isn't irritating.
