All good things must come to an end, even shows about dapper cannibalistic serial killers that never got the audience they deserved.  When NBC announced earlier this year that they would not be renewing Hannibal for a 4th season, I held out hope that the cult-favorite might find another home on a streaming service or cable network, but as time has gone on, that's looked less and less likely, and I've had to come to terms with the idea that this season's finale may be the last.
