Sometimes. I read as a student a highly recommended physics book. It looked all like gibberish. I reread it after mastering the material (from other sources), and it just was gibberish. So sometimes it is the book. (this happened because it went through like 23 editions and edition 20 was a 'modern rewrite' which killed it. The reputation and praise was gained from the older editions).
