I don't watch much tv - but I make an exception for True Blood!!
I like the fact that Sookie is a strong female character.
Also, I like the fact that I am able to engage in "willing suspension of disbelief" as the characters are true. For instance - Sookie is probably high school educated. She is intelligent, but not well schooled. Her vocabulary, actions and behavioiur all reflect this. All the characters are written in acted true to character and circumstance.
Anyways, I find the series great fun!!
