The storm was great, but there was one other scene that had as much or more LFE in it, but I can't remember off the top of my head what it was. All I know is, I rewound it and listened to it a few times
It was later in the movie. The DTS-HD track is awesome, period. The surround activity was great.
I would put this one pretty high up on my list of favorites from Pixar. The video quality is damn well near perfect, as expected.
I'd call this one a MUST SEE.
