The Visitation continues to be another great romp in this season. The team lands on Earth in the wake of crashing aliens that promise to wipe out the world with disease. I couldn't love this TARDIS team more and each of them shine greatly here. Nyssa shows her technical skills, Adric (barely) manages to fly the TARDIS and Tegan gets controlled (but she does manage to snap out of it!). This is the end of the Doctor's sonic screwdriver too, which does actually have consequences starting from this story. The sets are beautiful, as is the android and the Tereleptil suits are also remarkably well done.
