A clearly passionate retelling of a woman's fight for answers and justice
13 March 2020 | by jtindahouseSee all my reviews

I stumbled upon 'Lost Girls' tonight on Netflix and thought it looked interesting so decided to give it a look. I wasn't aware of the story behind it and I wasn't aware that it was based on true events. The main thing you'll notice when watching this movie is that is has an agenda, and it pushes it very heavily - and I liked that because it was personal. When a film just picks an agenda and decides to shove it in your face, that's garbage. But that isn't what happened here. This movie has a reason to be anti-police based on the real-life happenings and it wants people to know that. I think it found a good balance between getting its point across and also making sure it didn't consume the movie.

If you asked people to list all the Oscar nominated actresses who appeared in 'The Office' I think a lot would forget to put Amy Ryan on their list. She is though and 'Lost Girls' is further proof that when she is given the material to work with she can act her backside off. Her performance means a lot to this movie because she is the driving force behind almost every scene. If she wasn't able to pull it off the movie would fail, simple as that. She is terrific.

If you don't know anything about the real-life events this is based on then this film works very well as a mystery-drama. If you do know about them then I would suggest you're still going to enjoy this film, just in a different way. Don't come in expecting action scenes and over-the-top drama thrown in for the sake of it. This is a low-key, understated film that just goes about its business and does so wonderfully well. I had a great time with this movie and I suggest you will too.
