"Subjective" =/= "Can't be bad"
The ship and stone thing was fucking retarded, makes zero sense and was complete soulless sosphistry that LOTR is not known for. It is not within the lexicon of dialogue or philosophy for the show. Characters in Tolkiens work, from the realistic, to the fanatical to the supernatural speak very plainly with a sympathetic tint that makes even the grandest points relatable, real and impactful.
Saying "A stone cannot resist the depths of darkness" or whatever the fuck that was for the most impactful scene to start a franchise was and is terrible writing. Whether you like it or not is subjective.
Yes. Galadriel being the best climber, best origami maker, best swordfighter, acrobat, master of the mystic, super-natural swimmer, smarter than everyone and generally a fucking annoying unlkable domineering cunt is Mary-Sue-ism. Legolas was probably the most over-powered character both in the novels and movies, but because he was a thousands year old hunter from Mirkwood and his specialty, from the jump, was designated as an elite warrior killer. Aragorn was of this ilk but many times would defer to Legolas, Gandalf and even Boromir for input, ideas and information. Legolas himself was even incapable of killing a troll on his own.
So you think that makes sense in the canon of the show? Galadriel, who is never mentioned as a warrior princess in the source material, is a more proficient warrior than probably the best humanoid killing machine walking Middle Earth in Legolas? So Galadriel is the most competent warrior in middle earth. It's settled. Just like Rey is the best Jedi ever.
You stating that you don't think something stupid even matters to the story is just your own obfuscation and we don't have to pretend it makes sense or is the general opinion of most. It seems like you have a lot invested in this show, and aren't even a huge Tolkien fan bc you have zero fucking clue what you're talking about, which is why everything you're saying is going to be chalked up to culture-war "Dunking on the chuds" bullshit.
