Agreed. I don't enjoy when narrator comments are so long that I feel like I have to turn on the text so I can read and get through them faster. I was impatient to play, and the narrator just kept going.
But for the most part, the long comments had to do with Graham's memories, feelings, and opinions. I'm always a fan of character development, and those comments fleshed out Graham's relationship with his family while immersing me in his emotional state at the same time. Though I did catch a long bit about a rock, and one about a tree.
So I guess have mixed feelings about the comments. Nice additions to the story, nice voice work, but still too long.
