- drug-use (including heroin injection and joint smoking)
- child abuse (physical, emotional)
- guns (and a suicidal fascination with them)
- attempted suicide
- drying-out in rehab
- self-harm (I think... not 100%, I might be misremembering - a lot happened in this book)
- suicide - including a VERY graphic image of Kurt's dead body.
You're dealing with REAL people here - have some f**king respect, please!
I felt like Kurt's mental health problems weren't really explained. We got one or two blink-and-you'll-miss-them references to his bipolar disorder, and that is it.
Now, given that Kurt Cobain committed suicide, and there's a chance that Boddah was a hallucination brought on by the bipolar (or, indeed, a hallucination brought on by the drugs, or a combination of the two,) some attention to how his illness will have impacted on both his general mental state, and his susceptibility to drug and alcohol addiction, would have been a good idea.
But there were also issues - and one's which can't be ignored; so give it a read if you want to, honestly, it's pretty fascinating, but do it with your eyes wide open.
