I expected more twists and turns, but I guess that's my fault, not the film.
This review may contain spoilers. I can handle the truth.
When they were wrestling for a gun to kill each other, but ended up making out on the floor, I proclaimed this the best movie in the world.
I stand by it. More famous french actresses than you can poke a stick at. Isabelle Huppert being the crazy, kooky aunt and giving herself a sexy makeover. Knocking out a drunk matriarch and stuffing her in the closet. Decades old murder revelations. It has everything you'd ever need in a movie.
