Are you genuinely saying that because I think this film will be shit (haven't seen it it's not out yet but I have read the awful books) is because I'm too old?
The short provocative answer: Yes, being too old might impair the enjoyment of Scott Pilgrim.
Popular and youth culture can be a series of elusive trends and as such their half-life is quite short.
So the big questions can the story reach you on a personal level?
I believe from my personal experience and some comments in this thread that it is less likely though far from impossible that the foundations of relationship in the early adulthood differ and portraying contemporary "mating rites" is what Scott Pilgrim is about.
Since I happen to know people, male and female, who fit some of the archetypes in Scott Pilgrim very well.
So is this unique to a current generation? Not really. It is more about your personal experience that effects your view on the movie and comic books.
Is this unique to the current generation? Nope, but I figure that relationships and the accompanying values have change over the time and as such the contemporary generation is more likely to reflect some of their own behaviour and identify themselves with the character better.
