No, it isn't like that. Destiny's story has a start and an end, despite the end not being the "true" ending. The complaints seem to stem from the the substance and quality of the story not being up to people's standards, so it's not the case of paying for a book yet only getting a chapter, but rather the case of paying for a book you were looking forward to, but it turns out to be lackluster, yet it's still a full book.
