The irony is that the character Tolkien created and Peter Jackson showed on screen was always the epitome of a strong character. Not just physically strong, but powerful in a way that meant she didn't have to fall back on physical strength.
Well, she had possessed a ring of power for a while at that time right? I think the series so far has done a great job laying out the background here. Hopefully we will get hints on how the elven rings actually helps their wearers. Was always a mystery to me. I have no problem with how Galadriel is depicted in the series and hope the rings and what they do will play the central role here.
May the bluebird of happiness twiddle your bits.
