RKMBs Forums .::Robegories::. Media Series Finales: the Good, the Bad the Ugly

With the finale of Lost tonight, I've been thinking of the various ways that long-running series have capped of their runs. Some have been great. Some have, of course, sucked.

Off the top of my head, here are the ones I've liked (in no particular order, though I'd probably put Newhart and the Shield on top)

• Newhart
  the Shield
  Magnum, PI
  Hawaii Five-o
  Six Feet Under
  The Sopranos
  Mary Tyler Moore
  Star Trek: TNG
  the Fugitive

Ones I hated (again, in no particular order, but I really, really, hated MASH and Seinfeld's):

• MASH
  Seinfeld
  Twin Peaks
  X-files
  Alf
