A good read
As the title states, however I only recommend that you read it if you can also get your hands on a copy of the other issues that are linked to this particular story arc.
The Joker's thugs dressing up as classic or vintage horror film monsters and villains as one of the many amusing features in this story, this chapter of the Joker's film-making plan is a recommend read.
It will make absolutely no sense whatsoever if you have not read the other Detective Comics (in this Knightquest sub-plot) issues.
Not very hard to find, worth the hunt if you plan to complete the small collection; I recommend this issue to all vintage Batman/Detective Comics readers!
