How did a major summer release, which must have gone through countless story meetings, test screenings and marketing strategy sessions, end up being so confused? (Maybe I just answered my own question.) This begins as a superhero satire, with Will Smith as a grouchy, underappreciated Superman type who hires an image consultant (Jason Bateman), then halfway through the picture turns oppressively serious, with more angst than Batman Begins and Ang Lee’s Hulk combined. With Charlize Theron; directed by Peter Berg, who strains against the PG-13 rating.
