The V miniseries was a rather unsubtle SF Nazi allegory, which replaces the Fascists with evil reptilian aliens and Germany with 'Merica.
When they finally remade V -- because why not? They decided to amalgamate several annoying and bland characters from the Roland Emmerich-esque cast of thousands that the original boasted into one super-douche bag, the teenage son of the protagonist. Easily duped into becoming a Hitler youth due to his infatuation with a hot alien blonde girl and some emo-bitchiness about an inattentive mother, somehow he becomes part of a confusing, convoluted, and utterly mystifying plan the evil aliens have for humanity.
For plot purposes he keeps getting worse as the series goes on, and naturally because he's the protagonist's son we're forced to care.
