The Story itself is not too much to write about I must admit, like there are some good solid Ideas here (especially around the End), but frankly it’s nothing that sticks too much out in my Mind. And this may sound negative, but I actually think It’s for the Story’s Benefit, then while it doesn’t strike me with a freshly new Story, it strikes me with great Character Chemistry, Character Moment and brilliant Dialogues.
Cornell shows off how well he knows his Tardis Trio of Benny, 7 and Ace here, all of them have such an electric Chemistry with each other and just feel rightly characterized. The Dialogue as well sticks out so well here, you get plenty of witty lines here!

That transformation Scene is such a good Cliffhanger and the whole transforming Idea is used rather well, I find. And I especially adore the longer Aftermath we have after our main Plot ends, it just puts the Story in a nicely tightly Place, which I like!
