To be honest, I've hardly ever seen an episode of this. The only one I remember watching was about Catwoman. Of course, the show's usually about real people, either historical figures or celebrities. I may have seen some other episodes, I dunno. But I have sometimes thought it's something I should try to watch. It's not really important to me, though. Which I feel bad about.
