I hate to badmouth the actress, but even from her first scene with the doctor, I immediately thought she was a really naff choice. It felt like they tried to go for an unhinged, threatening, almost dictator-like leader, but she didn't even come close to being able to pull off those vibes. Maybe something Rosamund Pike-esque from Gone Girl would've been better - icy cold, detatched yet calculating who can explode in an instant would've been more unnerving. Well at least she's over and done with already.
