The Seeds of Doom is many aspects is a pivotal point in the show’s history. Veteran director Douglas Camfield makes his final contribution to the show history and Sladen had announced her exit from the show at roughly the same time. The Seeds of Doom takes The Doctor to two corners of the Earth in the space of six episode where he battles a whole series of menaces; a plant-based alien who can destroy the entire planet, a millionaire, insane botanist who actions are driven on the basis of greed and power, and a trigger happy henchman who becomes an unwilling ally. The design work in renaissance era continues to the models shots and extensive location shoot at Athelhampton House for the majority of the last two episodes. The cast are continually strong, and the first two episodes are some of the best in the show’s history. A witty, dark humoured script from Banks Stewart, he appears to be more focused on his ideas this time compared to Terror of the Zygons and closely shot studio scenes all make for a continually brilliant viewing experience. There is so much that can be said about The Seeds of Doom, but one would have to watch it to understand and appreciate its sheer brilliance. *****​
