It's not an A grade movie by any means, but it certainly doesn't pretend to be.

I do have to wonder if there's multiple low reviews because the ending wasn't wrapped up in a neat little package, and a lot of people can't cope without a happy or closed ending.. and I get it, it was a bit frustrating to not truly know what happened, and the very end was a little confusing as it went from fiction to not entirely fiction to breaking the 4th wall and accusing a UK politician of being involved in child sex trafficking, and abruptly cutting..

But the film itself overall was an interestingly written story with multiple twists, and for once, no actual gore (except the ending where someone is shot point blank in the head out of nowhere), but otherwise, it's the cleanest crime story I've seen in decades.

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.

I don't understand the negative reviews except for the fact that people must not understand the film. I guess it's because you have to listen and pay attention to what is SAID. There are no crashes, explosions, or gratuitous sex scenes so it loses their attention.

It is a very intense subject matter and touches every emotion, you really never expect some of it. As for some saying you don't know who the actual culprit us, I believe it is answered by the last phone call by the female detective if you really pay attention.

I recommend this for people who like intense crime thrillers, but realize it has the potential for triggering (in I hate that word) subject matter.
