In short, it's called maturing. You can't expect the man to stay 16 - 17 years old forever.
Just like everybody who doesn't stay playing with action figures (or whatever) the rest of their lives. We all grow up and think different. Movies like, "Are We There Yet" have gained Cube a whole new generation to come (longevity.) ...but from the looks of it, some of you refuse to grow up & fail to see the big picture.
