One of the best serials I have seen so far. We finally get to see the origin of the Daleks, and are introduced to Davros, their creator. The Doctor seems to kind of fail in this episode, which is unusual

The Time Lords basically hijack what he is doing to send him on an errand to stop the creation of the Daleks, but he is very unprepared for this. Both the Kaleds and the Thals are working against him at various points of the story and in the end he only manages to delay the creation of the Daleks.

Davros is really what makes this episode shine. Through Davros we see why the Daleks are so hateful, as well as their other mannerisms like lack of mercy and way of speaking. Davros appears to die in this episode, but I expect we will see him again
