It has little mathematical content and as anaphor pointed out in a sibling comment is is not even an accurate portrayal of Russel's and his contemporaries lives. I think trained mathematicians and the philosophically educated are probably just not the right target audience for the book. I still found it an interesting and entertaining read. Just a few days ago I gave it to my eight year old and she came up with a lot of good questions while reading it. It is not a children's comic though and it is definitely a book that needs guidance, especially because of the artistic liberty it takes in many respects. For example, the first thing I had to set straight is that Russel's brother was nothing like he was portrayed in the book.
