Survivor 16

Lost


Then somewhere a little further down;

The Shield
Blake's 7
Six Feet Under
Prisoner Cell Block H
Southland



I'm expecting great finales from;
Breaking Bad
Dexter

and Sons of Anarchy

Lost's finale was good. The Big C's was good as well because

Finales I'm expecting to be good
Big Bang Theory (When it ends down the line, I won't be surprised if Penny gets a Nobel Prize for something about living with geeks and nerds. Maybe Leonard marries Penny, Sheldon loses his virginity to Amy. )
Dexter
Breaking Bad

The Spartacus series finale. The series was hit or miss, but the last episode was the greatest television ever made bar none. Worth watching the whole show just for that

Most critics agree as well, it's not just me. Highly recommend
