Felina is the series finale of the television show Breaking Bad.
The Showtime series Californication was designed from start to make any season finale work as a series finale, in case of early cancelling the show
After its fifth season, the sitcom Reba was in danger of being cancelled as a result of its original home, The WB, being replaced by The CW in September 2006, and the resulting uncertainty over which WB series (as well as which series from CW co-predecessor UPN) would be carried over to the new network
