so... magneto tracking down rogue, using her powers to turn the world's ruling elite into mutants... how's that about logan? And dept H, kidnapping chuck, using timmy the mutant to make chuck kill all the mutants... how's that about logan?
You could just as easily say the first movie is about rogue coming to gripes with who she is and finding acceptance since you know, the movie opens with her and all the characters do what they do because of her.
The second movie spread time around and had some major character arcs for several characters.
The X-men movies are no more "about" Logan than STNG was "about" picard.
In both these movies, logan is just there for the ride. He doesn't save the day, he's not the focal point of the story, he's just the most popular character.
there's a difference between seeing the story through a character's eyes... which is what singer said about Logan, rather than the story being ABOUT a particular character.
