Thanks! The funny thing is that with most of us, we saw the TIH at a very young age (younger that my wife's cousin who's 10 yrs. old). As we age, it's harder for us to look at some aspects of TIH with with more "matured eyes". The Danger/anger sign was something I just remember as part of intro, and just accepted it at "face value". She was looking at it with a different perspective (after she saw the third episode).

By the way, while my kids are 4 years old and have developed a keen interest in super-heros (they know a bit about the Hulk), they haven't seen the Avengers yet. Speaking of new converts, my sons have, however, seen a bit of the show. They watched part of "Ricky". The saw it from the part where he and Ricky share a drink together. They were quite intrigued (my wife, who had not actually seen that episode before, found that scene very amusing too). They watched it until the end. They found it rather exciting! I was concerned that the Hulk's anger might be too intense but they know he's a "good guy".

I'm holding off on emersing them completely into the show, but I like that the seed of interest is there.
