Overall, this commentary is rather well done. Bruce does an excellent job at providing an insightful commentary, and has a very strong command of the history, geography, and culture of Palestine and Rome, and the persons mentioned in the book of Acts.
It is especially interesting to see that Bruce seems to be rather Pentecostal in his interpretation of the outpouring of the Spirit passages. However, he avoids popular phrases such as "the baptism of the Holy Spirit" and "initial evidence" and the like. He also shows that he seems rather open to such a modern phenomenon, citing the biography of Sundar Singh, who was a missionary in India claiming to have had a Damascus like experience where he saw Christ.
However, some of the commentary seems a little lacking. The last 10-15 chapters of the commentary seem a lot skimpier than the earlier parts. Perhaps because there is not as much controversy with these parts, or who knows, maybe Bruce was under some sort of deadline. This is the main reason I don't rate this commentary 5 stars.
