I saw this one last year at VIFF, and I liked it too. I like that the directors starts in the middle of the whole plot, which allows the audience to dive into the story, and I really like the ending. That said, I grade it lower, as it is about 6.5/10 for me. I like it, and I do not think the story can be told any better, but there is a limit to these stories, and the directors did as much as they could with it. It is good, but not exactly a can't-miss.
The directors and the lead actress were there at my screening, and I quite enjoyed their Q & A. Rohl has a really bubbly personality, which really surprised me. They also revealed that for one of the scenes in a very frigid warehouse, Rohl had to shave her head three times, because her hair continued to grow. They joked that they are pleasantly surprised to learn that your body will try not to let you die from the cold.
This one is also filmed with actual celluloid film stock, and they much prefer it. In fact, they said they would probably never go back to digital again.
