This would be a 3- in my personal rating system, where 3 is middle of the road and a 2 means "didn't like it." This is another of a gazillion cases in which Goodreads not allowing half stars (and thinking that a 2 could ever mean "it was OK") is problematic.

I was hesitant going in because of the early/heavy buzz and the content (depression and suicidal ideation). When my hold came up and I started logging it, I realized that I had already read (and not particularly liked: 2+/3-) another of Haig's books: How to Stop Time. That being said, this neither upset nor thrilled me as much as it did either for others. Frankly, I'm unlikely to continue reading Haig's work—it just doesn't do anything for me.
