I don’t really have any thing else to add on the Galadriel front that wouldn’t be pedantic disagreements for the Sake of it as we just see the character different.
But as far as Kratos goes id agree that the first game isn’t great story or characterizing and is more so just a foundation. Though I’d disagree that story and characterization isn’t strong in the series as a hole the problem is mostly that getting a deeper understanding of Kratos isn’t in the main 3 games and it’s chains of Olympus ghost of Sparta and ascension which really flesh out the story and him as a character.
But Kratos is of course very off topic.
