Leagues better than the previous two parts. Earth has been taken over by the Daleks, human resources have been depleted so now they are tempting Sontarans to the planet for conversion. The master is working with them of course. Having an older Molly makes narrative sense and a an acceptable workaround for not being able to get the real deal. It is fantastic seeing the master's plan come together - he takes over a Dalek army! The way he betrays the Dalek leadership is very satisfying and MacQueen's performance is once again, perfect.
