The Amazing Race is back, which means it's time for these teams to address their UNFINISHED BUSINESS...at least according to the producers. It's not an all-star season, as some of these teams finished in 5th place or worse, and it's not a fan-favourite season either, as at least two of these teams are comprised of people that were nearly universally loathed in their respective seasons. Instead, we're given the subtitle "Unfinished Business"; in other words, these are teams that were eliminated thanks to some stupid little mistake that they made, and this (presumably) is their chance to redeem themselves.
