I have nop;roblem for renaming categories, but I do think that it would be good to have "type" categpories as well. Some people only like one or two types and might have feel discouraged looking thru something like Charlton, Quality or Fawcett for a type of story. A few categories might ioncluide the following:
Super-Heroes
Western
Horror
Science Fiction
Literary Adaptations
Kids
Movie Adaptations
True Life
Romance
Action and Adventure
Historical
Etc.you get the idea I think.
