It was ok, but given how much people go on about this book, it didn't live up to expectations.
Specific things that bothered me:
Generally portrayed differentiation in a negative way, as something difficult that can be useful. No interesting ways to get around this and e.g. keep more able kids occupied.
In the SEN section, portrayed ADD/ADHD in a purely negative way, as a problem. Did not mention hyperfocus, for example. Did not seem v compassionate.
In SEN section, did not ONCE mention ASD. Like, !!!
Although generally advocated against shouting, seemed basically happy with it and didn't problematise it much.
Noted the possibility of kids suffering abuse as an afterthought, rather than an important thing to look out for.
At one point suggested talking to the class about a kid's behaviour when he wasn't there. At one point suggested treating a kid with pity. Both of these suggestions are disrespectful of students as people and, imho, not OK.
Also, the structure didn't seem to make sense. For example, the chapter on why poor behaviour occurs was Chapter 8, while the chapter on First Lessons -- a more specific topic -- was early on. The chapter on SEN was very late on, possibly the penultimate one, reinforcing the position of students with SEND as marginal. Putting it earlier might have encouraged people consider accessibility as a fundamental part of classroom management.
