This is a German film about a high-strung perfectionist cook named Martha. The movie title gets it right the trailer (and the poster) doesn't. The trailer's scenes were chosen specifically to deliberately mislead the viewer into thinking this is a romantic movie about Martha and the gentlemen pictured. Not at all, it's Mostly (about) Martha. The man shown in the scenes does not come until later into the movie and he has a small supporting role. That being said it's relatively good.
Also the usual cooking movie warning applies: There will be delicious food being shown so remember you may salivate with hunger after watching it.
