I'm writing this review as long distant philosophy graduate who's recently been thrust into the maelstrom of teaching A level philosophy of religion. As such, it is an excellent resource for teachers.
Each of the key debates in POR are given a chapter by assorted professors who, even handedly, summarise the key issues, give background and (usually) offer their own perspective on how to resolve them - and 'resolve' is the key word.
Most of the issues in this branch of philosophy are variations on the question, "How do we square the infallibility/omnipotence of God with this philosophical question..." Be that divine foreknowledge, life after death, the problem of evil and so on.
The chapters are variable in quality, as you would expect, and there aren't that many philosophy professors who specialise in this area. It hasn't been hip to be a philosophical theist for a long time.
A level students will find it too challenging on their own and (I suspect) that decent undergraduates will find that it has sacrificed breadth for depth, but for teachers like me it offers a rigour and fresh perspective that monographs like Vardy (valuable though they are) cannot do.
