BEST: Cersei

WORST: Daenerys/Sansa/Jon Snow

Diana Rigg is so good. Nails it every scene
I don't like Jon Snow's.

Best - Lena Headey
Worst - Kit Harrington

Best: Lena Headey (she deserves an Emmy)
Worst: Emilia Clarke (Dany is such an amazing character, and she is ruining her )

Best: Alfie Allen by far, he saved the North last season.
Worst: Kit, Emilia, I would say the sand snakes but they never got a chance to begin with so.

everyone in here saying Emilia Clarke is a ki - you people literally have no clue what you're talking about, you're just regurgitating opinions/posts from reddit (which is pretty much all ATRL is nowadays) and you can't tell the difference between bad acting and bad writing

Best : Lena Headey, Sophie Tucker, Michelle Fairley, Aidan Gillen

Worst : Emilia Clarke by far

Best - Carice van Houten
Worst - Liam Cunningham

I though the same about writing until I watched Terminator and she wasn't that good there. I'm not saying she's the worst actress ever tho, she has had her moments but compared to the other MAIN characters, she's just there. Anyway, I think she's way better than Kit tho.

Best - Cersei Lannister
Worst - Jon Snow

Don't get how people can say Kitt/Jon Snow. He's done as much as he can with a calm, reserved character, and I at least find him 100% believable and immersive in the role (never seen him outside GOT so idk, maybe he sucks generally?)

For me, Emilia/Daenerys has the biggest discrepancy between what the character reads like on the pages and the actress' performance, and is the only major character I can think of who I've been like "oh, I'm watching an actress performing right now", but in fairness Daenerys is probably an incredibly difficult role to make believable, requiring a range of emotions and character traits that not even a nuanced villain like Cersei possesses.

Best performances for me out of the living would be Cersei. I also loved Tywin and Catelyn... Honestly, this show has such a good cast, I really can't think of any "Bad" actors, just occasionally bad puss--uh, writing.

Also, while I let the eye color go, I really HATE the decision to leave Daenerys's eyebrows dark brown, it always reminds me that I'm watching an actor wearing a dyed wig So yeah, the makeup/costume designers failed her as well.

Samwell Tarly is the worst actor, if you see the guy's interviews he's exactly like him irl.

Melisandre's the best actress though. Her change in S6 has been amazing.

THIS! Underrated as fk. She's not given that much to work with but when she is she is incredible. To look like that but to act like a great mistress beyond her years (as her character is way older) is amazing, and I'm not gonna lie it made so much sense when we found that out.

Obviously Cersei, and IDK what this anti-Emilia Clarke thing is all about. She does incredibly.

Best: Lena Headey, Alfie Allen, Liam Cunningham, Charles Dance
Worst: Kit Harington, Aidan Gillen

omg same but i feel like if her eyebrows were the same color as her hair it would look like she was an eyebrow-less alien

This 100%. My straight friend could not stop dragging Daenerys because of the eyebrows I think that got him more emotional than most of the plot.

I dont watch the show but Jon Snow is sexy beyond belief so i vote him for being the best
