I did a similar top ten list through the first two seasons here.
Honorable Mention (just missed the list):
He just hasn't done anything substantial as of yet. I have a feeling that he'll continue to get a bigger role once all of the storylines start to collide but as of right now, he's on the outside looking in.
Quite possibly the coolest looking character right now in Game of Thrones. Giantsbane (where do they come up with these names?) is a the leader amongst the Wildlings group that scaled the wall with Jon Snow. This guy's beard game is on point and considering at least half of the characters have some kind of facial hair on this show, that's saying something.
And there's this.
Brienne of Tarth
Hailing from the Sapphire Island of Tarth (not real Sapphires mind you), Brienne of Tarth is as imposing a woman as you'll come across. She'll hold her own against the boys just maybe not against the bears. We last saw her last season alongside Jaime Lannister as she escorted him across the country as her hostage in service to Catelyn Stark. Their scenes and bond became my favorite thing about Season 3.
She's now back in King's Landing with no one to fight or orders to take right now. I hope she doesn't waste away up there because she was certainly a great part of last season.
Jorah Mormont/Grey Worm
I would have just put these two here with Daario Naharis but it looks like they just changed the guy who was playing Naharis to the guy from Treme/Nashville. I liked the original guy last year but they didn't even try to make these guys look even a little bit alike. I haven't been the biggest fan of the guy playing new Naharis from things I've seen of his in the past but I'm hoping to God that this ends up working out. Take a look at the two actors:
Old vs. New Daario Naharis:
Sooooo, ummmmmm, yeah. It turns out that the actor from last season was cast to be the new Transporter so he couldn't film GoT for this season. His loss.
Hopefully the new guy can fight like this.
Daenarys Targaryen aka The Mother of Dragons aka Daenarys Stormborn aka probably a lot of other names
She may not get naked as much as seasons passed, but as long as she had her Dragons, she's going to remain bad ass. It's always a lot of fun whenever you come back to her storyline and that's very telling as to how much you like her. You're always wondering what's going on with her Dragons and army of ex-slaves. I'm hoping that by season's end, she can get to mix it up with some of the other characters that we've come to know because he story seems to be separated from everything else that is going on in the Seven Kingdoms each season.
It seemed like Tyrion got all of the best lines for the first two seasons but now Bronn looks like he's getting most of the humor between them in their interactions. Plus, he's a kick ass fighter and he has a way with conversing that grabs your attention. I almost wanted him and The Hound to fight right before Stannis' attack on King's Landing started. Almost.
Again, I'm probably listing Tywin too low here as I did with my last top ten list. He's absolutely one of my favorite characters on the show and the interaction between him and any other Lannister is must-watch, incredible stuff. I think I'm just ranking some people higher than him because they're so fun to watch explode on other people and Tywin is a more reserved and yet still imposing presence on the show. There's no way he should be only fifth in the rankings, but I already wrote all this so I guess I'll stick with it.
It definitely says something when all of his kids shake in their boots whenever they have to talk to him and he has to do is give them a look and they shut up right quick.
The Hound has become more of a central character and I, for one, couldn't be happier. You could tell that there was something special with him from the outset but having Joffrey publicly berate and boss him around could only last for so long ("Fuck the King"). Now him and Arya look like they're going to be the Jaime and Brienne of this season and do their best imitation of a buddy comedy as they trek across the Seven Kingdoms.
Tyrion has a small fall in the rankings since the Blackwater episode at the end of Season 2 mainly because Shae has taken up at least half of the scenes that he's in now. Couldn't she have just listened to Varys and gotten on that damn ship? Tyrion is still a clever wordsmith and is always on top of his game, but I've begun to gravitate towards two other characters since last season as my new two favorite. That's not a knock on the half-man, but more an endorsement of the other two.
It's weird to be rooting for a little girl to become a vicious killer right? Like, I find myself being all psyched when she kills somebody but then re-thinking it since she's like 11. Nah, come to think of it, I'm cool with her becoming a killer. After all, all of her brothers are killers and her father was a killer, right Hound? Plus, all these people had it coming...so far. She's a bad ass character and she gets to learn from one of the best killers in Westeros now. I'm all for as many scene between the two of them that they can fit into this season.
I might be in the minority to have Jaime as my favorite character but I can't help myself, even though I'm not really digging his new hair cut. They should have kept it long like it was last season if you ask me. I like the way he talks. I like the way he fights. I like how he can twist your words around just like he can twist a knife in your belly. Jaime took the reigns as my favorite character in his redemption as a person in the last season. It's funny how I can forgive all of his terrible transgressions from the first two seasons with a couple acts of unselfish acts of kindness. Oh well, I guess that's who I am (at least from a TV watching perspective).
Now that my top ten favorite characters are out there, I just wanted to get a couple of my least favorite characters off my chest. The only reason Joffrey Baratheon isn't on here is because he plays the despicable little shit of a King so well. There's not a single scene of his that you would fast-forward through if you were re-watching a season, that says a lot. Doesn't mean I don't want to punch him in the throat, but he's really good at what he does.
Middle of the Pack characters that didn't make either list: The Tyrells (Loras, Olenna, Margaery), Davos Seaworth (read much?), Ygritte, Stannis Baratheon, Oberyn (as of right now), Hodor, Bran Stark, Daario Naharis, Cersi Lannister, Jon Snow, Littlefinger, Varys, and probably like 1,000 other people on the show.
5 Least Favorite Characters:
All she does is cry and complain. Enough with the blubbering. However, she is 18 now, so if she gets naked like everyone else in the cast next season, she could sky rocket on to my top ten list.
You might be like, who the shit is that? She's the sister of the warg kid from Love Actually who is traveling with Bran. I don't like their storyline at all and she's the worst person in it so she gets this spot. That smug smirk she does is just asking for her to get slapped.
This storyline is already so old and tired. It's the same thing with every interaction between her and Tryion. I'm hoping this doesn't go on too much longer because she's really bring the Imp down.
The kid playing Ramsay was my favorite character on the show Misfits so it KILLS me that he in the worst storyline of last season. Literally all that happened was that he tortured Theon...for the entire fucking season. Not furthering of the story there except for torture for like 8 episodes straight. It fucking sucked to watch. Just sucked.
He has been my least favorite character for every season so far. Just a big sour puss who whimpers at literally everything. It's unbearable. Now he has a sidekick in the girl with the baby and the scenes are almost unwatchable.
