My girlfriend and I just watched about 4 of the serious. Perhaps I shouldn't comment, having not finished it, but the series feels so disingenuous. The show reveals the mother lying about her daughter's past, so the filmmaker begins to make the whole series about herself. Like the part about the dig. She finds what are obviously animal remains, the S&R lady texts them to her anthropologist friend and we hear nothing more about it. It just felt a lot of smoke and mirrors that detract from the truth. She complains about dishonesty and bad leads, but does the same thing by entertaining every scenario, no matter how outlandish. If any truth were in her tangled web of bad actors, we'd never know now. It makes for a good documentary, but she clearly leaves a lot out to pull the viewer in, at the expense of seeming boring or adding relevance to the missing girl's actual disappearance.
Yes, I believe in corruption. Yes, the truth is often stranger than fiction. But perhaps this case is simply one of lack of evidence and the police don't have enough to entertain much discussion. Either way, this series wasn't the best way to attract attention IMO.
