What's funny is that you can't trust either side with historical figures. He's gonna paint himself a hero and his enemies will paint him as a demon. It's somewhere in between in most cases, though in Caesar's you can't deny the death toll
He made odd movies since he's no longer playing Harry Potter. This is Guns Akimbo like the other person said. I recently saw Horns that he made. He randomly grew devil horns after his girlfriend died. He seems just to be picking roles that interest him instead of trying to chase money.
The two movies are good, if you don't take them too seriously. I never saw Harry Potter, so I can't compare, but his acting is good. The storyline is worth a watch, imo.
