If you've seen the rather impressive trailers for this weekend's new adventure film, 'Sanctum,' then you know it's the story of a team of expert spelunkers who become trapped deep inside one of the planet's biggest cave systems. Going just by the trailers and TV spots, 'Sanctum' looks exactly like the kind of movie that a mom and dad could bring their 14-year-olds to see: a non-kiddie adventure flick that's still "grown-up" enough to be cool.

Oh, except that Universal is releasing its "big 3D adventure" movie with an R rating. The MPAA says the R is for "language, some violence, and disturbing images," which pretty much describes every PG-13 horror film I've ever seen. So why would Universal unleash a big-budget, James Cameron–produced 3D exhibition with a R rating that they easily could have trimmed down to a PG-13?
