Hmm, I'll just go through my Hulu favorites list. There may be some duplicates that you've already watched on there but...
Unfortunately, some of these shows have seen their finale and some only after a season or 2.
The Pretender (loved
The Invisible Man
The Finder (so mad they only made one season, but with MCD dead, it would be hard to keep it going)
Vampire Diaries (guilty pleasure
The Tick (so utterly stupid and ridiculous that I can't help but love it)
The Crow: Stairway to Heaven
Eureka (pissed when they ended that one too)
Beauty and the Beast
Also, one that is truly awesome that you can't find on Hulu (not sure about Netflix) is Game Of Thrones.
Also, Dexter is incredible...though I missed the entire new season.
