Being Jewish, I have a bias towards liking a film like this. The usage of Yiddish, along with the many exaggerations of the Jewish family are something most people won't understand, unless they grew up around it. Parts of this film I found to be hysterical, while my non-Jewish friend, sitting next to me, didn't get it at all. As for the film, it's a lie before the credits even stop rolling. Keeping Up With The Steins, really has very little to due with the Stein family, as they are part of the background story at best. The film is actually about a broken family, forced together on the eve of a child's Bar Mitzvah. Benjamin Fiedler (Daryl Sabara) is turning 13, which in the Jewish religion means that he is about to become a man. His parents are well off and are making huge plans for the event, but Ben wants no part of it. In an attempt to take the attention off himself, he sends an invitation to his estranged Grandfather that he's never met, a Grandfather, who shows up to the families wealthy neighborhood in an old RV, with a woman half his age. This is where the heart of the story comes from, as father and son are forced together after fifteen years. Jeremy Piven stars as the son and believe it or not he's a big time Hollywood agent, living in a life of luxury. This toned down version of Ari is forced to see his father, played by the legendary Garry Marshall. For the past 15 years, he's been living as a hippie, teaching on an Indian reservation. As soon as they see each other the two are at odds and it really is very funny. The star of the film is Spy Kids, Daryl Sabara, who I have never liked. He's just always so shy and painfully awkward, I really just don't understand his appeal. While he is a major part of the story, the parts of the film that feature him without Marshall or Piven are just painful. Keeping Up With The Steins isn't raunchy and much of the humor is intertwined in the Jewish religion. If you're not Jewish, you'll probably have the same reaction my friend did. Personally I loved it, but I can understand how this film won't appeal to everybody.
