Another astounding boxset.

The Doctor, the Master and the other time-travelers in this series actually think like time-travelers, which is refreshing. Experiencing things out of order, dealing with incomplete knowledge they know they'll gain later, logic-ing out their situation with an awareness that time is not linear (whether it's a time-hopper catching up to a ship at the end of the universe or a future creature sent to the past to become its own patient zero). It's not unique to this boxset or to the audio genre in general but it does seem to be handled best by Big Finish. It's something I wish the show itself leaned into more frequently.

Time travel stories should exist right at the edge of comprehensibility and so far Dark Eyes does.

Liv Chenka is immediately an all-time companion. Someone from the future, viewing present-ish day earth as ancient history, with concrete skillsets (medical care, piloting) that actually factor into the plot. Excited for more.

The only critique I would offer is that, occasionally, this Master is difficult to hear. I feel like I need to turn up my volume three notches whenever he speaks just because of his volume or because of his particular voice. Not sure what that is, but it makes parts difficult to follow when you are, say, walking a dog and can't fiddle with the volume between lines.
