Nah. Cera was perfectly cast probably one of the greatest casting choices ever made. Scott's a manipulative human dumpster fire and Cera portrayed that perfectly.The movie erased most of the women's personalities and screen time and snatched Ramona's big moment. Also Michael Cera as Scott was terrible casting
Scott's actually attractive and charismatic, but an asshole at first. Not believable with Cera
As a tight one movie adaptation of a multi-work series it managed to hit almost every major beat. It's not perfect, but it's as close as it could be.
