Empty-headed

Tom is empty-headed.

She always tries to appear more empty-headed and frivolous than she really is.

Never has a group of actors uttered as many mealy-mouthed platitudes as you'll find bouncing off the walls of this empty-headed film.

Hill, though, captures the entitled, empty-headed viciousness of the wealthy elites the film tries to eviscerate.

“Doesn't matter. That man is not the leader.” “But he is the main guy on the show.” “He is an actor, Nandor. A simpleton who paints his face. He is an empty-headed puppet who thinks the world loves him, when in actual fact, he is nothing more than a lapdog begging for scraps.” [groans] “No, he is not the leader. That would be another devil who pulls the strings. The halfwit they call the director.”
