Y'know... I don't think this is so terrible. Yeah, they were incredibly stupid and got into a hot mess, financially. But they didn't blame other people for it, and they are doing things pretty differently now, it seems. And they're doing the show so they can help other people avoid making the same mistakes, or fix them if it's too late for that.
I'd rather watch someone turn their life around, like this seems to be, than watch a show about people who live ridiculously and present it as desirable (i.e., most reality shows).
