Ted Mills’s review published on Letterboxd :
Hard to discuss this Diane Kruger-led film unless you can talk about the final moments and whether they make sense with all that's come before. However, I must admit that because Kruger's character is so distraught and so realistic, her decisions in the final third cause an incredible amount of suspense and tension. Does she know what she's doing? Does she have a plan at all? It doesn't seem like she does.
As a film however, is this all the film is set up to do? Provide us with a logical path to a desperate act? It's like when you watch a short film and realize the whole thing is designed to make the twist pay off.
Kruger is all in for this role, and the insight into the German legal system (the courtroom looks like the final room in 2001) is fascinating. I left the cinema rather unaffected.
