Starz network has a TV mini-series spin off of the movie
Crash. On it Dennis Hopper plays this character who is a raging N. IMO, he is a classic example of what the most malignant Nism looks like up close.
Also, the HBO mini-series,
Trueblood, a modern day take on vampirism, directed by the guy who did
Six Feet Under, has some interesting perspective when it comes to Nism. Although, I haven't singled out a particular character who is particularly N, (I have a hunch about the bar owner), the entire modus operandi of the vampire both emotional and physical are based in the principles of Nism, the manipulation, the drawing off of another's energy/essence, the deception, the predatory nature.
Both shows are somewhat "out there" but I find them to be an interesting referendum on Nism when viewed from a psychological perspective.
There's also,
The Hills on MTV. That guy Spencer, Heidi's boyfriend. He's not a character. He's a real life N-in-the-making. He's only 20 something, but he is hard core N. He's an emotional abusive boyfriend, controlling, manipulative, overly sensitive, rageful and arrogant.
I just got Comcast On Demand Service. I don't watch what's on anymore, I parouse the On Demand list and watch whatever. My curiosity generally gets the best of me and I can't resist a new story.
Random.
Just thought I'd share.
