This movie is carried by Kathryn Davis as Eva. "Eva loves life, darling, and she's not afraid to live it." And it's fund to watch her live it. Why she sets her sights on Lucas baffles me, but the world definitely needs people like her. There is an exchange where Lucas accuses Eva of "doing it for money" and she responds that she has to eat and pay the rent and he doubles down on the accusation. By that point in the movie, it's clear money isn't what motivates her, and Lucas should be able to see that.
Olivier Renaud, as Lucas, is a cold fish in this movie. He never really shakes that even as Eva supposedly reforms him. There really isn't chemistry between the leads. And Lucas' response to all Eva does makes no sense. Whatever response he makes seems to be mostly internal. While Davis carries the move, Renaud holds it back.
Still, it's indicative how appealing Eva's personality is such that the movie is still enjoyable.
The story premise is a slight twist on the trope where a cabin is double booked for two strangers. In this case, it's Lucas' condo.
