FULL SPOILER-FREE REVIEW @ https://www.msbreviews.com/movie-reviews/somebody-i-used-to-know-review
"Somebody I Used to Know presents a cast packed with chemistry and holds interesting themes, but the formulaic screenplay lacks depth and greater care regarding character treatment. Dave Franco and Alison Brie manage to convey meaningful messages about the dilemmas that arise when mixing individual ambitions with love life, but at the cost of conflicts and drama forcibly provoked through awful human actions without any kind of heavy consequences. Secondary storylines linked to sensitive topics are approached in an exploitative, even childish manner. A movie of phases that falls short of its potential."
Rating: C
