The point was the progression of characters into adulthood. Iceman was a lame character in the beginning, Angel was lame character. They grew into more interesting characters with years of stories and adjustments. I am not arguing all the characters are good, I am saying you can see the potential in a lot of these characters as adult characters. But the fear of over aging their cash cows makes them never age up young characters like they should even in case where it is clear they are future like with Franklin and Valeria in FF.
