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.
Being Human
The Pretender (
loved this one)
Heroes
The Invisible Man
Haven
Life
John Doe
Bones
Arrow
Grimm
Covert Affairs
The Finder (so mad they only made one season, but with MCD dead, it would be hard to keep it going)
Journeyman
Alphas
White Collar
Burn notice
Vampire Diaries (guilty pleasure

)
New Amsterdam
Kyle XY
The Tick (so utterly stupid and ridiculous that I can't help but love it)
Castle
Royal Pains
The Crow: Stairway to Heaven
Monk
Psych
Eureka (pissed when they ended that one too)
Supernatural
Beauty and the Beast
Breakout Kings
Justified
Fringe
The Following
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.
