Good acting from the lead (which was the reason I clicked on the title) the mom was a strong character who didn't have some special skills but stayed focused to escape and to be with her son. I loved the scene where after she saw another victim (that talked to her) drowned (not to death*) she broke down and had to stop for a while. The movie communicated her emotions and her will really nicely. The ending was okay; some disliked the ending but I felt her lingering love for her son tied the whole movie together. I was SO UNCOMFORTABLE throughout the movie because I shared the anxiety the character had. I feel like the movie wanted to showcase something beyond the plot.
