Watched Pixar's 'Up' with my kids on the weekend. We had it quite loud. I went upstairs during the movie to get them some snacks and all of the sudden my kitchen floor is shaking and feels like the house is exploding. I went running back downstairs and ask my son what scene just played.
Long story short - the scene where they escape the bad guy and the rock pillars start falling over like dominoes. The kids loved the bass too so we replayed that scene 3 times before finishing watching the movie! Now that's a proud parenting moment!
