Sadly he wasn't the worst part of the film. He actually fit his role pretty well. The main female lead was pretty damn wooden. I was totally expecting my feelings towards the leading roles to be reversed but I actually think you'd have a better film if she was replaced rather than Jared. And I hate him in most things. I do think however if you replaced him in blade runner 2049 it'd be a better film. Even though he fits that role really well, probably better than the one in Tron, he's still the weakest part of that film specifically.
