Thematic group

This tag is provisional. It is applied to a review when its subject work forms part of a thematic group (commonly a trilogy not united by plot or characters) together with another reviewed work. Where no other works in the group have been reviewed on this site, the tag is not applied, and counter to intuition, it is not applied to the earliest work in the group under any circumstances, because it characterizes the relationship between a later work and its parent, not vice versa.
