I really wanted to like SICP and I probably would have if I read it 15 years ago. I started reading it last month and I found it to be too broad. It covers too much interesting mathematical principles and then jumps to the next one right when it starts to get interesting. In other words, it's too shallow.
It probably doesn't help that I've seen many courses/documents that are (in hindsight) derivatives from SICP, so I have the nagging thought "not this again" when a topic is introduced in SICP.
