This is now my favorite commentary on Revelation. He is readable and lucid, as well as being reasonably detailed. He compares the views of different commentators, including Beale and Aune. He compares most options on difficult passages before coming to his own conclusion. This is not a starter for the student, but it will serve you well over the years, as you will refer to Osborne again and again. He is very good on the Greek and the Greek is transliterated, so he will still be OK if your Greek is not up to scratch. Footnotes are kept to a minimum and textual variants left to the back of each section. I found him highly readable. Scholars will like him and I also highly recommend Osborne for students, teachers and preachers.
