I just listened to Kenneth Branagh's THOR commentary, and I'd have to suggest everyone else who appreciates quality commentary do the same. I've not listened to many in recent years, as I've been burned by dull tracks and commentary that demystifies some of my favorite moments, often to the detriment if my enjoyment of a film
With that said, Branagh's track is a joy to listen to, it's consistently informative, fascinating and focused. Branagh doesn't just narrate what's on screen, he speaks at great length about his process and various aspects of the production as if he's drafted a plan for tackling the track before he ever showed up
If an Oliver Stone or Del Torro track is an A+, Branagh and his THOR talk gets from me a B+
