People in third-world countries are less eager to see movies full of angst over existential problems, and who can blame them. They've got other fish to fry. They'd rather see a few great dance routines and the guy end up with the girl.
People didn't suddenly wake up one morning and unanimously say 'I'm fed up with midbudget dramas. I'm only going to see action tent poles from now on!'
In a recession, people want to be told for two hours that everything is going to be OK. They want to escape from their humdrum or painful reality into a feel-good drama, or a love story that transcends their daily life.
Human nature stays the same, the one thing that stays constant, like death and taxes. And people still want good stories!
