1. Justin Richards doesn't take the obvious path of being blindly pro-tech or anti-tech, but delivers a more nuanced picture.
2. He also has a great ear for dialogue, both internal and external. Sarah, the Doctor, and Harry's voices ring true and clear.
3. The villains aren't your typical cyborgs, an imaginative choice.
4. The story is, at least in retrospect, a very amusing and incisive satire of 90s business culture.
5. The choice to explore the emotional impact of time travel, seeing an old friend suddenly aged or suddenly young, gives the story a lovely emotional resonance.
6. Sarah Jane gets some truly kickass moments.
1. The prose is a bit off. You cannot grin or smile dialogue, and there was one point where somebody shrugged with their eyes or their eyebrows that jolted me out of the story to try to attempt that for thirty or so seconds. There's definitely a sort of eyebrow motion that goes along with a shoulder shrug, but it doesn't really work without the shoulder involvement. Anyway, I spent too much time thinking about this, which in my opinion is an indication that just saying that the character had shrugged would've worked much better.
The cover art is kind of hilarious. The reptilian cyborg is pretty cool, and okay, I guess the CD was a plot point so it can be on there, whatever. But then the Doctor shows up in the background, pretty clearly having been drawn from one of the first publicity shots to pop up on Google (or whatever we had back in the nineties; was that Ask Jeeves?), but in such a way that half of his face looks furious and the other half looks about to weep. Meanwhile gun-toting Sarah Jane's head looks too small for her body, or possibly it's just that certain parts of the body seem a bit overlarge--methinks the artist forgot which brunette he was drawing once he got past the neckline and starting going for Peri.
