Here is the thing about the Brienne and Jammie sword fight. It looked choreographed, and I really dislike it when a fight looks too choreographed.
Yes, Brienne uses brute force over finesse, as she is a large woman and all that Armour wears anyone down. And after a year of captivity, Jammie is a bit rusty and weak from lack of proper food and exercise. So I understand Jammie not engaging Brienne until he figured her out. But if you think about how fast Jammie moved when he took Brienne's sword from her, shed his cloak and cut the robe all in a single move, that is how the scene should have played out. Show us Brienne matching Jammie sword strike for sword strike and skip all the pretty stances that don't mean a thing in a real fight. Other than to show your opponent which leg you'll lead with...
I was in the SCA, many years ago, and excelled at two sword and great sword. In one-on-one melees, I would dance with my opponent to start with, watching their foot work as well as their eyes, to figure them out, as they did me. But you can't tell how good someone is just by their stances and counter stances. You have to engage and Jammie never really engaged Brienne with too much seriousness as he would in a life and death situation. IMHO.
Look at when Jammie fought Ned, there was no slowness to the engagement, no dancing to figure out Ned's weakness, and a whole lot less talking. Ned is a large man himself and moves about as slow as Brienne, and yet, Ned held his own for the most part against Jammie.
I guess the sword fights of early Earl Flynn movies spoiled me, they looked very plausible and at full speed.
I do agree that the actress portraying Brienne is doing an excellent job...
