eh, some lines just fall flat and he doesn't sound like he's even trying ("Everything. Everything there is" "Don't tell anyone, I have a reputation to maintain") though he nails others ("Distrusting me was the wisest thing you've done since you climbed off your horse"). The Wire shows that Aidan Gillen's obviously a brilliant actor, but, along with Lena Heady as Cersei, he's one of the two people I'm not entirely sold yet in their portrayal of their character. It might be because the characters in the show are actually written slightly different, however, so my expectations for them are thrown off; they're showing less of Littlefinger's humor and charm and more of his sleaziness and resentment, and the show's Cersei seems a good deal more competent than the book's.
The whole cast is pretty goddamn amazing, though. I'm liking Charles Dance (Tywin Lannister) already. And while Renly annoyed me in the scenes with Loras and the hunt, I really liked him in this one with his (brief) confidence.
Got chills in the final scene, with Eddard, Littlefinger and Varys marching into the throne room, with Joffrey sitting on the throne being declared king, Cersei and Sandor beside him, the Kingsguard before him, and the ominous bell echoing outside... amazingly tense atmosphere.
