Although he features in episode one, this is the episode where we really get to grips with Davros. He is clearly modelled on a Dr Mengele-type figure but instead of just being ugly on the inside his twisted form is an expression of his twisted ideology. Hey! but don't let that put you off, this episode is great fun, moving along at a fair clip.
The situation becomes more tricky for our heroes as The Doctor and Harry are separated from their time-ring (and thus unable to get back to the Tardis) and poor Sarah Jane has her own adventures with Mutos, Thals and Distropic weaponry. The freeze frame cliff-hanger is particularly effective.
