I think a younger audience (teens - mid-20's) might be jaded with the quality of TV shows and movies. They have grown up in an era where they can get whatever they want (entertainment-wise) at a touch of a button (or touchscreen). They have been exposed to year after year of the newest tech, the newest entertainment trend, the newest 3D games and movies.
However, we of the older generation can remember the low-quality Hulk or Spider-Man TV shows of yore. We remember Pong and Pac-Man. We remember the occasional offerings of Christopher Reeve's Superman (yes, a great movie for its time - - but then parts III and IV came along - - *shudder!*) and Batman of the 1960s. So when we get all these (in my opinion) quality movies and all these (in my opinion) quality TV shows currently being thrown at us by the handful, we are really appreciative and made hungry for even more.
