It was a good ending to the show. If the show had continued I think they would had to get rid of a couple of characters and add at least one new major character to fill the void of the character or characters leaving. The Samantha and Jack relationship story arc was getting old. They could have had a story arc with Martin getting promoted and meeting some upper level FBI woman that he gets involved with had the show gone on. But I don't think the Danny and Elena Marriage story would have been very interesting had the show gone on. Vivian could also been promoted to a new task force that looks over specific kinds of missing persons cases like they had her do with that sex slave ring a while back if they brought back the show.
