Jake is dead. Elwood decides to get the band back together. Along the way he meets John Goodman, Joe Morton and a kid. You had to know this movie was trouble as soon as you they put a precocious little kid in it. The Original Blues Brothers had no place for a kid.
Kids get in the way of large car chases and seedy music.
Then you've seen this one. Once again, they go to great lengths to find a place to fit the same people in the movie. There's Aretha Franklin. There's James Brown. There's Frank Oz.
