​Require all TV-shows to film “a final episode” so that series that expect to be continued, but are cut for whatever reason has a decent wrap up!

Edit: A final episode after every season.

Ever wanted a satisfying end to Firefly, or any number of good animes, or when we realize that the last seasons of a show are so bad that they should not be spoken about (Game of Thrones) we can insist that the final episode of season 4 has a somewhat satisfying end, and we can forget that all the rest of the bullshit was ever proceed.
