You're blowing this out of proportion.
It all starts with two elementary school boys. One hits the other one in the face with a stick, and thus begins the grueling visit between both sets of parents. Penelope and Michael Longstreet (Jodie Foster and John C. Reilly) invite Nancy and Alan Cowan (Kate Winslet and Christoph Waltz) over to discuss this altercation between their sons. Of course it turns into a slight scuffle of their own.
It's hard to do a movie where the characters remain in the same room for the entire time. The dialogue really has to be strong to keep it interesting, because the change of scenery sure isn't. Luckily director Roman Polanski accomplishes this with ease. Reilly and Winslet were the shining stars in this film for me, they had the best lines. I can also say this is the first film of Jodie Foster's that I've liked in a long time. Christoph Waltz, as always is good at playing a complete dick. All of the parts suited these actors well and in my opinion, the ending was perfect for the film.
