There was an intensity in "Bloodhound" (aka, "The Lost") that was compelling. But the film's protracted use of flashbacks from the "party" resulted in a major shortcoming with the pacing.

At a posh gathering, a young girl is kidnapped right out from "under the noses" of her parents. Or, was she? During the interminable flashback scenes, the filmmakers keep changing the narrative. By the end, it is still unclear who was responsible for the tragic disappearance of young Olivia.

The characters, including the parents, their guests, and the sister were uniformly reprehensible and disgusting creatures. There was a clear intent to raise consciousness about human trafficking. But the film was mired in misdirection and a determination to avoid shedding light on who were the actual perpetrators. This was most apparent in the vague and conflicting impressions of the nanny, who fled the scene, left the country, then apparently told a fictitious story to the authorities.

The best character development was Detective Holloway, the career-driven workaholic. It was not plausible that he would browbeat the parents to the extent that their civil liberties were likely violated. But the actor's performance of Holloway was superb.

Overall, this was an average film, but worth a watch for the intensity of the investigator Holloway.
