Oh I stirred up a hornet's nest now
He's a shitty actor. He's overly dramatic, overly maniacal, he over-delivers virtually every one of his lines. His on screen performance isnt scary, not intimidating, not sociopathic....it's hokey. Whatever sense of horror I guess I'm supposed to feel because of this supposed psychopath, is lost on me as his lines, his expressions, his inflexion, are so.....forced, it's dismissive.
I'm certain the reader fan-boys will come and rush to defend the character and how he's portrayed in the books, but regardless of how it's supposed to be, it doesn't translate to the screen at all. I blame the actor.
