Superman is arguably the most popular superhero out there. He saves the day over and over and over again. He is almost impenatrable (despite the fact that he can get killed by kryptonite, more on that later) and a great role model. Unfourtunatley, he isn't given much vibe here, becuase Superman Returns is one boring actionier. Although it is age-appropriate (see exceptions below) it will not appeal to the die-hards at all. In fact, many times it is melodramatic and not fun at all. So this is best left to the open-minded. Content issues are few, but there is a talk about "pleasurable sex with the big hero" and a violent scene that is worth covering the kid's eyes. [spoiler warning] In it, Superman is beaten, battered and stabbed ruthlessly with kryptonite by Lex Luthor, falling to a watery fate (he gets out).
