Childs honestly admits that "the purpose of this book is unabashedly theological". As is expected from this author, his aim "is to seek to interpret the book of Exodus as canonical scripture within the theological discipline of the Christian church" (which means, of course, his version of theology). This may disconcert those who do not agree with his precise shade of liberal evangelism, especially in the sections headed "New Testament Context". However, once this hurdle is overcome, this book is packed with useful information. There are few if any thorough textual and philological studies of Exodus, and the notes here are probably the best available on these topics. The sections headed "Literary and Traditio-Historical Analysis" discuss (among other things) the Documentary Hypothesis, but Childs is not overly concerned with this aspect since he is more interested in the canonical form of Exodus. The most valuable parts are the "Old Testament Context", which discuss the meaning of the text and its relationship to the rest of the Old Testament. These sections, plus the extensive textual and philological notes, constitute an excellent commentary on Exodus and fully justify buying this book. The other parts can easily be ignored if you disagree with them.
