Yeah Cena has grown in leaps and bounds as an actor. Even the growth in his skill from The Suicide Squad to season 2 of Peacemaker is really visible, and that’s because of the work he’s put in to keep up with some of the other actors. He’s great case study in someone with some natural talent who’s pushing themselves to become good. But yeah I’m bit biased as he’s the only guy I could see playing Carrot in a Discworld Guards movie and I really want that.
