Sam was initially dissatisfied with moving to Santa Carla, mostly because of his grandfather’s lack of a TV (as Sam stated MTV to be among one of the things he liked — with another being comic books, especially the Batman ones).
He had remarked that Star’s parents were ex-hippies, and she had asked him what he meant by that.
In the movie, he is the epitome of the saying “Still waters run deep”.
He was said to be the de facto “leader” of the Lost Boys.
Much to the surprise and disappointment of Sam, Grandpa showed that he preferred to read the TV Guide instead of owning a television set.
He felt that family was very important, and he also felt his “boys” (David, Dwayne, Paul and Marko) needed a mother to keep them in line.
Being brothers, Sam and Michael were teenagers with different interests — Sam with his comic books, and Michael with his exercise equipment.
Michael was puzzled when Grandpa asked him about that.
She loved her father, despite his eccentricities.
Edgar told him “Try the holy water, death breath” before throwing a handful of holy water in Paul’s face, which made Paul shriek in pain.
