This was a surprise; much better than I was anticipating.
For a movie that deals with the topic of underage prostitution, it manages to keep an even tone. Though it takes many twists, and slips into some dark water, it never goes anywhere unforgivable. With as many movies as I have watched, I thought I knew full well where this would go, but it surprised me.
I initially wanted to watch this for Alexandra Daddario; sadly, she's barely in it. Now, the actors who are in lead roles did a great job, mainly Katherine Waterston; she carries the film from start to finish.
Back to the story itself: While the filmmaker could have easily lead the viewer down any moral/ethical road, like with any great art, it is left to the audience to draw their own conclusions. The story is just allowed to play out. There are moments of comedy here, but the roots are always firmly planted in drama.
As a tip to potential viewers: Don't expect loads of graphic nudity or sexual content. There was really only one nude scene - with Waterston... worth it - and it was quick. The sex that transpires is either off screen or not filmed in an explicit manner.
The drive here is the story. If you're so inclined, _The Babysitters_ is talking about some ugly and sad aspects of life, but again, not beating you over the head with it.
