What Haz said.
I've been known to watch a movie because of one particular actor or actress, but it's usually at first. As you watch a film, other actors come on the screen and, sometimes, you become interested in them just as much as the actor/actress you came to see.
Watching a movie and not caring for the story, its other characters, or the other actors portraying them, then it's just silly.
