The Good Stuff:
The use of the "urban legends" theme led to some innovative and funny encounters. C'mon, how can you hate seeing Slimer blown up in the microwave? I think my favorite might have been the kids turning themselves into bombs with Pop rocks and cola.
A lot of action for Ray and Egon as they essentially have to take over the business themselves due to Venkman and Winston's little diversion into politics.
Winston gets a nice, meaty role in this story, and I think I like the idea of him keeping up on government affairs--the idea was presented and explained quite well. . I had to admit a pang of satisfaction at the mention of Winston's dad as working in construction, though.
Slimer. I'm not Slimer's biggest fan. I barely use him in my stories. But I was nevertheless strangely pleased to see him in this book--maybe just because he IS such a lightning rod to people who hate the animated series. But here is Slimer done right: the gluttonous babbling mascot palling around with Ray and annoying Venkman. He doesn't talk clearly, he doesn't zoom in and save the Ghostbusters from Xanthador; he was handled perfectly.
The Not So Good Stuff:
Xanthador seemed pretty much your stock "self-aggrandizing evil overlord with semi-competant help" type villain that we've seen before. He gets a little more interesting with his gambit posing as Goodraven (even if I saw that coming 1.609 kilometers away, as Egon might say) and I thought there were a few neat twists toward the end. Using a planetarium to create the stellar alignment he needed was a great idea; defeating the fear demon with raw courage was, again, maybe a bit predictable, but was satsifying anyway.
Used the Janine/Louis romance from GB2,
. They did kind of subvert it later in the book, though
Some sloppy editing--Takes place two years after GB2, but Lapinski is mentioned at one point as having been Mayor for "ten years" even though he's clearly NOT Lenny from the movies.
