I forgot to post this earlier when I finished, but I found Book 2 excellent. He is so good in juxtaposing the mundane stuff with big thoughts. I was drawn by his relationship with Linda, even though there's nothing particularly different about it; it's just life. And I sort of really like Geir.
There's a wonderful passage where he freaks out about one of the kids making a huge mess at the table while eating, and then he realizes he is acting like his father. His commentary is so poignant - the idea that you can rationally identify what's happening, but can't escape it. Anyways, it resonated.
And here's a story: I was in Norway a few weeks ago and was asking everyone, somewhat obsessively, about their views on the book(s). Expectedly, it is very divisive. But one of the people I met was really angry at Knausgard for what she believed were deeply inaccurate and unfair portrayals of regular people. Norway being such a small country, everyone knows someone who knows a character from the book. Anyways, this woman apparently knows one of Karl Ove's love interests from his college days in Bergen, and swears that he invented most of the stuff. Jeffrey Eugenides tells a similar anecdote about a dinner he had with Knausgaard in his review of Book 4 in the Times. Anyways, I don't think it changes anything regarding the book, but it raises some interesting questions about the boundaries between fiction and life (I like that James Wood basically treats Karl Ove as a fictional character in his New Yorker review).
