No where in ANY text was Galadrial a warrior, so was describe as an amazon, yes, but that doesn't mean a warrior, her only involvement in a battle was tearing down a fortress with magic. She was also married to Celeborn in this age, and they had children one of which was a daughter that married Elrond, we know this. She was one of the oldest Elves, we know this, older than Celebrimbor and Gal-Galad, yet in the show she is depicted as younger than them both, and "brash and full of piss and vinegar" which she certainly wasn't in this age as she was looking to rule in this age with her husband. No where in the text did she go to Numenor, or interact with the "queen reagent" Mireil (who never was queen reagent, she was supposed to be but got screwed over). Elrond was also the first one to suspect Anatar of being Sauron, not Galadrial.
That is some of the issues from text with ONE CHARACTER. I could go on, but why should I when neither you nor the show runners did your research.
