“ The Taste of Things ” should come with a warning: Audiences may be tempted to abandon work as they know it and start a beautiful, calm new life in the French countryside devoted to the culinary arts. There is something rather cruel about releasing a film this lovely and voyeuristic in the dead of February, in which the cinematic gardens are lush, the game is fresh, the atmosphere is tranquil, the distractions are non-existent, the conversations are intellectual and the goal is shared. But maybe that’s why we need movies like this.
