I would say Matt Damon doesn't have a huge range. You either like him or you don't. I think he is getting much better with age. Oppenheimer, Ford vs Ferrari, the Instigators were all stellar performances. I think he struggled with the Departed.
I also know his classmate from Harvard who said he was a jerk with a giant ego. I don't trust her 110%, she also has a big ego, but sounds about right. Overall, with his activism, Jason Bourne dark charm, I take him any day over Vincent Vaughn.
