Yeah, and there's no reason it needs a PG 13 rating, or a PG rating, or a G rating, or an NC-17 rating. Financially, sure, but if these types of films are to be taken seriously they should get R ratings, otherwise they will continue to be comic book films and carry all the connotations that such a label brings. Just like with Batman, if they want to integrate the best villains while still remaining faithful to the source material, much of which is pretty great, the R rating allows that, but it isolates audiences. They want to make a great film, they would benefit most from an R rating. They want to make a film that can be good, maybe, and make a good deal of money, then I guess go PG-13 until the franchise wanders into mediocrity.
