Back in the 1960s the series The Fugitive had a great final episode that wrapped up the story satisfactorily. Than the studio found that the series was much less watched in syndicated reruns than shows that did not have concluding eps. Thereafter the studios began deliberately disallowing final series wrap-ups. Thankfully, some series makers started wrapping series again, but some still adhere to the other idea-- and for good reason. While series wrapping hasn't seemed to hurt the several Star Trek series, others seem to have no value in syndication. Who wants to watch the series Lost go through it's laborious tedium after it's miserable final season wrap-up? (Not me).
