I'm still trying to figure out how they'd handle Kingslayer if they chose to go beyond the first book. Martin somehow managed to make me kinda like the guy, which is pretty amazing, all things considered. Without being privy to his thoughts and perspective, I'd imagine he'd seem like an even bigger asshole. Although, on further reflection, that's not necessarily a bad thing, although it'd certainly take an adjustment on my part. It probably doesn't matter at all for Game of Thrones, since Jaime doesn't do anything remotely redeemable in that one anyway.
