If someone would pay for it that is. Then again, we would have lost a lot of the drama, if that was the case from the start (you'll have to watch to see where this is heading and if there are solutions). Also why not occupy an apartment? And make love in it and other things. Speaking of which: The movie contains a lot of nudity and adult situations as they are called.
But it's not so much about love, than it is about perspective. About how 3 very poor people, who don't seem to be able to get along with each other at first, do struggle to make it and to survive. And what they have to do at times (how society is seeing them and "handles" them). So there is more than just the naked flesh here. But it may not be enough for some for various reasons. It's a drama first and foremost and it puts its finger on a wound that I'm not sure can be healed easily
