My son Jonathan loves superheroes just as much as the next 9 year old boy. I was a big comic book nerd myself (and still am) back in the day. This summer we have the pleasure of having 4 superhero movies. 3 of which are direct from the comics- Iron Man, Batman (The Dark Knight), and The Incredible Hulk. (the Will Smith acted Hancock being the original material) He has been relentlessly bugging me that he wants to see these films.
Sadly for Jonathan all 4 movies are rated PG-13. Which basically means that I have to watch all 4 movies before I allow him to see it- just to be on the "good parenting" side of things. I'm fairly sure he'll be fine (altho, his 7 year old brother may not be) with the cartoonish violence and sexual innuendos. After all, he's still a well adjusted kid after seeing all 3 Spiderman movies and the Transformers. Movies that had impalings, all around scary moments, kissy-poos and masterbatory jokes. I'm also fairly sure that he knows more than he lets on. Even still, I sense that the birds and bees talk is right around the corner.
Looking back, I recall seeing R rated movies while I was under 13. My friend Adam was the rich kid who had a Beta-max (lol) before most of us even knew of VCR's and we got to see movies like Animal House, Airplane and Caddyshack on video tape. I may be a sick twist, but I doubt my mental illness is derived from being exposed to breasteses at an early age. Heck, my dad even had a subscription to Playboy and I got to sneak in his room and got many a gander at the Full Mindy. Later, as I turned 13, my family splurged to get cable and the PRiSM premium channel. I eventually discovered the wonderful world of soft-core porn that was readily available at 2AM. Thus I know know that If I'm not careful with Jonathan's internet activities he will eventually be exposed to free online porn with animals, foot fetishes and bukakke parties.
Unfortunately for me, I really don't have the time to get to see the movies in the theater anymore and I was a BIG movie goer before rearing children. I'm sure as both kids get into their tweens and up, I'll be able to expand my movie viewing pleasure and be able to go out to the theater more since they will be able to go with me. I believe the first R rated movie I saw with my Dad at the theater was Revenge of the Nerds. I think I may have even glanced over to see if he laughed at the "hair pie" joke for his approval. I felt more "adult" that day for having been viewed as someone who can be mature enough to handle frat party immaturity.
