The idea of young boy arriving at the age where he is considered a man is celebrated traditionally by Jews. In this age of consumerism, most 13 year old boys are given lavish feasts in which expense seems to be no object by parents that have the means to do so. The feasts evidently must have a theme. When we first meet the people in this mildly funny movie, they are in the middle of a bar mitzvah with a Titanic theme. We watch as the young boy arrives in a replica of a ship posing as Leonardo DeCaprio and even colliding with an iceberg. This party cost about half a million dollars to Arnie Stein, a Hollywood type that can well afford it. As Benjamin's own bar mitzvah approaches, his parents, Adam and Joanne Fiedler must make a decision about how big a party they want, and what theme will their son choose. Benjamin, who appears more grounded than his Hollywood agent's father, only wants to have his paternal grandfather, a person he has never met, at the party. Benjamin plays a trick by sending Irwin Fidler an invitation with a date of two weeks before the actual event. Little prepares him for the character his grandfather turns out to be. Irwin, who left his family when Adam at a young age, comes to town with his New Age-type girlfriend, who goes by the name of Saved Feather, to stay at his son's mansion. This brings back bad emotions Adam has kept bottled inside him. He can't forgive his father for what he, and his mother Rose, had to endure. The old man is a changed man and his love for his newly found family serves to get Adam's forgiveness. Garry Marshall steals the show with his Irwin. Mr. Marshall knows comedy well and knows what buttons to press to put the audience in his pockets. Doris Roberts is tremendously appealing as Rose, the wife that has had to endure a lot after Irwin left her. Jeremy Piven and Jamie Gertz are perfect as the parents facing a dilemma about to go broke in order to keep up with the Steins. Daryl Sabara is an excellent actor who shows he knows what he is doing. Daryl Hannah has some good moments as the evolved New Ager. Larry Miller and Richard Benjamin are seen in supporting roles. Basically, there was no cussing, sex, or violence to mar this nice piece of family entertainment.
