There ARE A LOT of bad movies like this. Just use IMDB to search 3 star movies and then look for 1 star monies. You will have to fllter 5 stars from every imdb post. Seems they start high to give these losers a going bang.

It looks like nobody has said Sweet Karma yet. Acting is pretty good and the main actress is really hot

try frozen 2010

Taken
it was much better than this one has a bettter ending.
shuttle could have been much better with a differenet ending.
it started very well, there were so many moments with real tension
thrillers of this type with no happy endinds are so disapointing.
this would be my ending
jules escaped from this guys, getting to the hospitall.
telling her story and then police comes mell and bad guys go jail

There's an extremely low-budget movie called Red Ridge that I found wellinteresting. It's got a very cheesy, C-Drive-In movie feel to it. Very grindhouse and exploitational but overall effective and disturbing.
I think Shuttle did a good job with walking this line and making it fairly classy, and it's a much more well made and acted film than Red Ridge. The big minus in Red Ridge is that the acting, save for a few of the villains, is REALLY bad.

The Nicholas Cage flick referred to above is probably "8mm". In 8mm the character of machine has some of the most wonderfully creepy lines of dialog I have ever heard spoken.
This film reminded me of movies like: Saw and Phone Booth where most of the action/drama takes place in a claustrophobic space.
It strongly reminded me of the movie Collateral where the protagonist is held captive by a deranged killer.
*Edit: I've only now realized the question is regarding human trafficking. Didn't "The Pusher" film series have some human trafficking going on? Many might disagree, but I thought Hostel provided plausible methods by which American and other affluent Europeans might be brought into the world of sex slavery or other maltreatment.

At the risk of SPOILING an important plot point
And Soon the Darkness. I dunno about the original, but the 2010 remake for sure.

Not the SAME theme, but a similar theme/story direction in the british movie Hush, you might like it if you enjoyed Shuttle.
A guy, while on the road, witnesses a girl, naked, locked in the back of a truck screaming for help, later on, his girlfriend is kidnapped
