The only person to truly appreciate the wily ways of “Synonyms” is writer/director Nadav Lapid. He’s using a cinematic space to explore the inner turmoil of a character stuck between cultures, and Lapid also provides commentary on political and military behavior as it factors into the history and future of France and Israel. There’s much to study with “Synonyms,” but Lapid has no interest in a straightforward understanding of a polluted headspace. He’s making a performance art piece with star Tom Mercier, chasing every whim to make the effort as unpredictable as possible. In that respect, the feature is an incredible success. However, without any triggering emotional involvement or showing interest in storytelling, Lapid has basically turned his therapy sessions into a two-hour experimental film, and not one that encourages viewer response.
