When a novel or series is anticlimactic, or gets really good and then just stops. A technique employed by author's to hold the readers attention, only to leave them unsatisfied.
In J.K. Rowling's series "Harry Potter", the reader experiences much suspense and excitement in books 1-6, only to experience literary blueballs with her unsasitfying epilogue.
