While Osbourne's speech is still slurred, he is much easier to understand than he once was, and he walks straighter and without as much of an amble. Fascinating footage shows how he prepares today for shows, with physical exercise and voice exercises.
Extra features are fairly sparse on the DVD, but include an interesting Q and A session with Jack and Ozzy, in which Jack explains that he wanted to make the documentary because he did not want people to confuse his father, John Michael Osbourne, with his stage persona, Ozzy, The Prince of Darkness. There is also a small segment on the Tribeca Film Festival premiere and some deleted scenes, of which the most touching is Ozzy talking about the death of Randy Rhodes.
While God Bless Ozzy Osbourne will probably not add any new information for those who have followed Ozzy's career from his Black Sabbath days until now, or for those who have read his book, the documentary is well worth seeing for the concert footage and interviews. That Ozzy survived, continues to perform, has mended his relations with all of his children and his siblings, and has a stable and loving marriage is a tribute to the underlying goodness and likeability of a man who surely stretched the boundaries of bad behavior as much as anyone can and live to tell of it.
