Unsubstantiated rumors aside, his douchey Suicide Squad antics, which reportedly included sending used condoms to his costars (something he later denied, but I could have sworn he himself admitted to doing it in the first place) definitely didn't earn him any fans, especially considering how the film turned out.

As far as acting ability goes, though, he more often than not knocks it out of the park, so I'm not worried about that.
