Deadly Assassin is far from perfect, and has a number of strange quirks to it, but by and large it is a very unique story from the Classic series that kind of has an irreplaceable, vital part of the franchise and its history. Sure, we had gotten scant glimpses of the Time Lords and Gallifrey up until now, but this is a whole new level, building so much into the world in these four short parts and bringing in a lot of new ideas and concepts to the franchise and the Doctor's people.

That being said, it is a bit of a double-edged sword. While Deadly Assassin does a number of things right, like getting into multiple chapters and the fun use of colour in their costumes to denote each character's faction and position in Time Lord Society, it isn't perfect either. The danger of stories like this is that they simplify the Time Lords a bit. I find it weird they don't have a word or concept of framing somebody for a crime to the point they have to borrow it from the English language according to the dialogue, even when they prove as a people more than capable of such an action. As always in stories like these and the Gallifrey series, the Time Lords become a little too basic and easily susceptible to manipulation when we subject them to stories like this, and I prefer the air of power and authority they are more generally given from a distance.

These are more insignificant concerns though, as Deadly Assassin is creative and entertaining, which matters most to me when evaluating something from Doctor Who. It is still held back by issues with its pacing, but it is an exciting story, a nice take on a politically themed thriller that is definitely worth checking out. It is weird to me that the Doctor is so unfamiliar with Time Lord politics here, and I think that was more done for the sake of exposition and the fact there isn't really a companion in this story. That's part of what makes it so unique and special though, the Doctor being involved in this story on his own without the usual support structure he leans on adds to the tension very nicely here. Still, there are a lot of good characters surrounding him in these four episodes and I really like the ending between the Doctor and Borusa alluding to their history. A great entry in Doctor Who history, to be sure.
