BAD THING: Ye gods, the bad artwork on the covers has infected the rest of the book! Why does The Doctor have horns in some panels? Did they forget to color the spikes in his hair or are those meant to be wrinkles? And what is with the random use of shadowing?
GOOD THING: At least the writing is still cracker-jack, with all the on-going threads of the book's run coming together and a surprise revelation that is actually a surprise.
The Final Verdict: Good story. Bad art. If you can overlook the later for the former, you'll be okay.
