This drama is populated by interesting characters, most of whom have well developed backstories. This is a nice contrast to the usual fare of superficial and boring people who are marched through a plot. They want better lives, make stupid decisions, get in trouble. But you can't help liking them, because really, don't we all want better lives? If you've ever bought a lottery ticket, you know what it's like to want to be a billionaire when you know there's no hope for it. So trouble comes, but everything works out well in te end. A simple drama with a good story, excellent character development, and a mostly happy ending. Really, what more could you want?
