Four of Monroe's major relationships were depicted in the film: Cass Chaplin (Xavier Samuel), Eddy G. Robinson Jr. (Evan Williams), Joe DiMaggio (Bobby Cannavale), and Arthur Miller (Adrien Brody), the latter two of whom she married.
Cannavale and Brody were both physically believable in their roles as DiMaggio and Miller. Still, for a film that was so bent on being outwardly emotional, it felt almost completely devoid of it in their performances. While there was plenty of emotion shown on screen, it's as if there was a glitch that scrambled the transfer of emotion from actor to audience. It's possible that I'm just completely dead inside, but as a whole, the emotion was never a sucker punch—it just simmered on the surface, never being brought to a solid boil.
As for Ana de Armas' actual performance as Monroe, it was about the same as her co-stars'; people seem to be a little quick to unequivocally applaud her portrayal because they're distracted by how much she resembles Monroe. Now, if this film got anything right, it's definitely the casting: de Armas was practically a resurrected clone, forcing me to genuinely question whether certain scenes were actually using archival footage of Monroe.
While de Armas' portrayal was certainly the best out of the entire cast, it—again—just felt like something was missing. In watching Blonde, I kept wanting to compare it to Spencer, a film with a similar set-up being that both give their full attention to a central woman being depicted.
As Spencer doubled down on its intentions to be a psychological, up-close analysis and depiction of Princess Diana, Blonde found itself lost in the mix. Kristen Stewart transcended the film in her portrayal—the sheer fact that she received an Oscar nomination for her performance while Spencer itself did not is a testament to that.
In that sense, Blonde's overall disorganized state overtook de Armas' performance instead of her portrayal being strong enough to lift both herself and the film up out of the chaos.
