Now's your last chance. The third and final season of HBO's "Getting On" started November 8, so you can still catch this unsung show while it's fresh. Why it never got the buzz of other HBO comedies is unclear. Sure, it's a funny show about a grim topic (dying), but that didn't stop "Six Feet Under" from becoming a critical and popular success.

Quality doesn't always mean popularity, as the following gallery of 10 currently underrated, little-watched series demonstrates. Granted, it's hard to make an emotional investment and time commitment to a show that might be on the cancellation bubble. So enjoy these while you can.
