Many years ago, DC Comics licensed properties from TSR, the role-playing game company, and produced, IIRC, four comics. One of them was based on Gamma World called Gammarauders. It did not sell well, and was scheduled to be canceled at issue 12, and the creators aimed to wrap up their storyline. However, it sold so poorly that DC changed its mind and decided to cancel it at issue 10 instead. The creators were unable to wrap up the storyline, so issue 10 included several pages of lightly illustrated text describing the plot to wrap up the storyline.

It would be great if TV show creators would do the same thing. I'm not suggesting they have someone narrate the plot at the end of the last episode, but posting a summary online would be excellent.

That said, there has been at least one instance of continuing a TV show as a comic book series: Buffy.
