It is common knowledge that the animated series franchise "Ben 10" has been aimed at the most childish audience and has lost much of its depth.

The audience that previously watched Ben 10 from the first to the ultimate alien ,grew up and matured. they still feel immense nostalgia from the animated serie.

The perfect solution would be an continuation or adaptation of the series, with a more mature content with the design of "Ben 10 Alien force" or such.
