“Sentinelle” (*** out of four) was a harrowing melodrama about a French solider (Olga Kurayenko) who returns home after a traumatizing combat mission and has to combat paralyzing symptoms of PTSD and anxiety while trying to re-adapt back to everyday life and then trying to track down the man who harmed her sister. Tense mixture of action story and mental health personal drama is held together by Kurayenko who is superb as usual and makes you overlook story weaknesses. Refreshingly compact and succinct also, at only an hour-and-20 minutes.
