There's a lot of toys and kids-focused merchandise at Toys R Us for Terminator Salvation (action figures, voice changer helmet, endoskeleton decals that make you look somewhat like a Terminator or somewhat like Seven of Nine). Remember when Terminator was an R rated movie full of people being violentlly killed by a robot in disguise? Now it's something that, through the toys, is being sold at younger boyswhich means the violence in the movies get toned down for lower ratings so those young boys can see the film and then buy the toys.

There's an adult audience for films like Transformers, and Batman, and Spider-Man etc, but there's also a child audience for them too and I think the balance is really hard for film makers to find.
