Of course, it's not all terrible. Carla Gugino actually makes good of her meager character and a few of the gags are actually extremely successful (especially the Guggenheim scene, which was just the right amount of ridiculous). In addition, the CGI penguins were undeniably adorable and surprisingly convincing. However, even though my target-audience-younger-siblings liked it, I do find myself worrying for the state of family cinema. If this kind of mindless, shallow filmmaking is what children are becoming used to seeing, more interesting family films are going to be come increasingly unaccessable.
Note: I have not read the book, but I have a hard time believing that a Roald Dahl novel could have been this vapid.
