Yeah, I'm not going to lie. The Forresters are little too StarksV2.0 for my liking. Let's see:
Father - gets betrayed and killed early on
Mother - "strong" matriarch; perennial poor decision maker; shops at same store as Catelyn
Eldest Son - takes up mantle as Lord of the House; becoming the center of a rallying cry against a Lannister-aligned House
Eldest Daughter - stationed in King's Landing; becomes involved in "The Game" (granted, she's more capable than Sansa)
Younger Daughter - more spunky and outspoken than expected (granted, she's not the tomboy warrior type that Arya is)
Youngest Son - curly blond-haired plot device
Other "Not a Son" - sent to take the Black at the Wall
Granted, they aren't carbon copies of the Starks, but considering how many other ways they could have written the characters, they are pretty damned close to them. I mean, they are even a noble house from the North, of all regions. The only ones that aren't really Stark clones are Asher and Ethan (and we all saw how that turned out for Ethan).
That being said, I'm hooked and eagerly looking forward to the next episode. I'd like to see how they mix things up a bit.
