resolve these storylines. The Australian soap opera Return To Eden ended in 1986 with a dramatic cliffhanger in anticipation of a second season. However, the network chose not to renew the show and so a hastily filmed five-minute "conclusion" was filmed and added on to the end of existing final episode to provide closure. Some shows, however, became known for never being resolved. In addition to the aforementioned Blake's 7, the supernatural series Angel, the original 1984 series V and its 2009 remake, all ended with unresolved cliffhangers. The cliffhanger has become a genre staple (especially in comics, due to the multi-part storylines becoming the norm instead of self-contained stories) to such a degree, in fact, that series writers no longer feel they have to be immediately resolved, or even referenced, when the next episode is shown, variously because the writer didn't feel it was "a strong enough opener," or simply "couldn't be bothered." The heavily serialized television drama True Blood has become notorious for cliffhangers. Not only do the seasons conclude with cliffhangers, but almost every episode finishes at a cliffhanger directly after or during a highly dramatic moment, much like the primetime soap operas of the 1980s and 90s. Commercial breaks can be a nuisance to script writers because some sort of incompleteness or minor cliffhanger should be provided before each to stop the viewer from changing channels during the commercial break. Sometimes a series ends with an unintended cliffhanger caused by a very abrupt ending without a satisfactory dénouement, but merely assuming that the viewer will assume that everything sorted itself out. Sometimes a film, book, or season of a television show will end with the defeat of the main villain before a second, evidently more powerful villain makes a brief appearance (becoming the villain of the next film). Occasionally an element other than a villain is also used to tease at a sequel. Peter Høeg's novel Smilla's Sense of Snow ends with a deliberate cliffhanger, with the protagonist and main villain involved in a life-and-death chase on the arctic ice off Greenland - and in this case, the author has no intention of ever writing a sequel, the ambiguous ending being part and parcel of the basic ideas permeating the book's plot. Similarly, Michael Flynn's science fiction novelette The Forest of Time ends with a deliberate and permanent cliffhanger: readers are not to be ever told
