Yes, The Simpsons has been churning out these annual, anything-goes Treehouse of Horror fantasy anthologies for XXIX years now. That’s astounding. And these installments always are among the show’s most inventive, because there are no rules, and most segments include the death of at least one familiar character along the way. Tonight’s show includes a segment spoofing Jurassic Park, in which at least one of the prize specimens is Jurassic, or at least geriatric, in her own right.
