Yeah I assume the laughing was because they thought the movie wasn't being serious. It was certainly surprising! (Obviously he wasn't going to let her be sacrificed, but I assumed there would be some happy ending Deus ex Machina stuff)
That was sort of my thinking. I expected them to figure something out the get the happy end possibly based on an overlooked detail earlier in the movie. But no such detail existed. They really couldn't fix the weather and save Hina. ---
