Saw the promo, watched the first five minutes and thought these autistic twins are fascinating, but their feats of memory turned out to be limited in this a B-grade documentary, but their manipulation as media freaks became a much more interesting untold story crying out for a follow-up.
Premise: a TV reporter in Florida "discovers" autistic twins with extraordinary memories and turns them into celebrities, not in a cruel way like Letterman, but nonetheless he cashes in on the fame of the Rain Man movie and promotes these gentle, likeable sisters in a series of news stories as savants, or geniuses with gifted mental abilities despite their disability.
They do have extraordinary memories based on their obsessions, but being able to name the day of the week for any date is fairly easy mental arithmetic if you can be bothered to learn the formula, and memorizing a limited period of 70s popular music or what TV presenters wore on any given day is less genius than obsession.
Where this documentary enters a very gray area is the twins' "worship" of Dick Clark, whose game show was another of their obsessions. The TV reporter takes them to visit Clark in episodes of their lives, but the documentary crew elevates it to a whole new level, filming the women on the Hollywood hall of fame, where they visit his "shrine" (the narrator's word not theirs). When they kneel at Clark's star, and profess love for their "savior", it's pretty obvious this is at the direction of the film crew, and this manipulative piece of television starts to fall apart and becomes more than just a little creepy.
