I'm not a fan. It's too much of a departure. The reworking takes a bittersweet but ultimately encouraging song and makes it sad. Going from major to minor neuters the sense of hope and uplift that builds throughout the original. In this way it violates the spirit behind Paul's purpose in writing the song: to comfort Julian Lennon. No thanks. A "Hey Jude" that doesn't aim to inspire is no "Hey Jude."
