Having listened to many of these Doctor Who novelisation readings now, irrespective of how good the narration is, The Auton Invasion is the first audio adaptation that has invoked so many memories of the story to the point that I will actually watch it again soon.
I have been through a real revolution with this story. Having read the book a few years before I saw the story, I was initially disappointed with the latter. And then with subsequent viewings I came to love certain aspects, which are actually missing from the audio. However there is different detail to the audio.
Also, it took me a few minutes to warm to this reading, and then suddenly I was really into it. John's impersonation of the male characters are rather good. I hope she gets, at least, to read the remainder of season 7 at some point.
This release is the first one where I feel I have actually got a worthwhile product (having already got the book and DVD). I therefore give it 5 stars. The original script is superb, the novelisation is great and the reading of said novel is really brought to life. If these three categories were applied to other audio readings within the Doctor Who range, then I believe the flaws start to show, as most only shine on two out of three.
