This was a PHENOMENAL episode, and by a new writer nonetheless! Really enjoyed hearing the Krynoid being vicious, while the human aspect of their transformation was really at the forefront. The Doctor was great in this, he really fit in well with the characters. I love the worldbuilding they've done its really been great so far, lets just hope part 3 is as good!

It was cool to learn that this is the Krynoid's home planet too was a surprise but rather obvious in hindsight.

The Doctor just leaving though felt a bit... Especially with how it ended!! 

Gutted Shearsmith's character is killed too, hoped he'd stick around for more.
