One thing to be aware of is that, other than the poem itself, a brief introduction, and some brief remarks by Robert Alter, the text consists mostly of very detailed translators' notes analyzing the verses line by line, even word by word. This material will be of interest to scholars of ancient Hebrew but perhaps not to the general reader. I read the book (sans notes) in about forty minutes -- and I have to wonder if I should have paid [amt] for the privelege. Nothing against the Blochs or their fine work, but I would have preferred more supporting material of more general interest.
