Lackluster Protagonist: Riri Williams, played by Dominique Thorne, is a brilliant MIT student, but her character feels one-dimensional. Unlike Tony Stark’s complex blend of arrogance, wit, and vulnerability, Riri’s portrayal leans heavily on generic “plucky underdog” tropes. Her motivations—grief and financial struggle—are relatable but underdeveloped, making it hard to root for her the way audiences connected with Robert Downey Jr.’s charismatic, flawed genius.
