I'm not a book-reader in regards to ASoIaF, but I watch the show and here's my commentary for the season finale. Note that this is mostly speculation, even though I don't think I'm actually spoiling much. If you haven't watched S3ep10, don't hover over these just in case.
Devos Seaworth is awesome. Which means he probably won't last the series, but you have to admire his character.
I feel like the only one not a big fan of Dany. I like Jorah and Barriston, and even the assassin guy they picked up recently, but I hate her individually. She has an interesting story, but I don't really care for her.
I love that Sam met up with the rest of the group and is actually being competent. I like his character, hope he stick around a while.
Tywin and Tyrion interactions are awesome.
I think Devos' decision to free Gendry will be a huge plot arc later in the series.
It was only somewhat surprising to learn the dude torturing Theon is a Bolton. Theon's a dick, but man, I hope the guy torturing has something coming to him too.
I think Sansa and Tyrion are starting to start a nice alliance, hope they keep it up. Varys was interesting in his scene, I still get shudders thinking about his revenge scene.
I hope for a huge no-holds-barred battle between everyone in the North and the Whitewalkers before the series ends.
As a side note, I was on campus the other day waiting for a class to start and I heard some dude talking about the books out loudly so that everyone could hear, and he dropped some major spoilers that really ruined my day. If you're discussing anything about this, keep it on the hush or warn people around you.
I wanted to destroy the freaker that ruined some questions I had in my head regarding the series a few days ago. That would be like if I came out of the theater after the third Star Wars' movie and said "Man, I can't believe he was Luke's father the whole time" in front of the line waiting to get in. No excuses, just a total dick move. Don't be this guy, because this guy totally deserves a lifetime of beatings.
