Well, I do have to say I was a little surprised when I watched this flying to Las Vegas in the summer!
Great, great film, but it's not one you can take the family to if you have younger kids. I would definitely recommend the youngest ages to watch this should be 12-13. By this time, children should be aware of alcoholism thanks to shows like East Enders and definitely Hollyoaks and also by this age, kids would have heard of a variety of drugs purely from watching the news or reading magazines and newspapers.
I wasn't prepped for just how unlike the other 2 films this was going to be! Don't get me wrong, absolutely loved it, our 9 year old loves Iron Man but I told the wife when I landed "No way! There is no way our daughter is going to be watching this anytime soon."
The reality is that Iron Man 3 reflects society in a grittier truer way, but I don't think littluns need to know about that at their age, definitely a 12 years old minimum!
However!!!!...... People need to stop bitching and whining to a degree and this is where proper parenting should step in. Robby Jr plays Stark down to a "T" across all the films. For those of you who don't know Stark from the comic books era: Stark is a borderline sociopath with narcissistic tendencies. He is an alcoholic and a womanising playboy bachelor millionaire. The only thing missing from his character is huffing up huge quantities of Tony Montana's finest Columbian, which, would have been a step far too far for Stan Lee to write about back in the day! He is a product of a neglected childhood to a degree where his father didn't have time for him (oh how that sounds all too familiar today!).
Tony (the character) goes through a transition across the Iron Man and Avengers films coming out the other side a better person all round. He has positives too. Not being technically a super hero he tries to change the world for the better with his fantastic intellect backing up the Old Days of Disney where school mattered much more rather than trying to sell sex, drugs and violence to youngsters.
Tip for the future parents. Don't take your kids to the very first week of showing, let adults test these films out first and then review them on places like this. But, in the UK the BBFC classified this film as "12 Certificated" and NOT "12A" (the difference is 12A means children under 12 can watch the film accompanied by an adult whereas a 12 is purely for these aged 12 and up). This is a massive failing of American certification as PG13 and 12A are the same thing. This should have been a 13 pure and simple, but then again, one of America's finest exports across the world is the glamorisation of sex, violence and the sexualisation of children (especially girls) on the silver screen and in the music business.
Parents across the world: do you job properly and watch films and listen to music first before your kids. If you let them listen to and watch Rhiana you need your head examined!
