When it comes to portraying the wacky, funny side of Doctor, Matt is good and will hopefully get better. The same goes for the Doctor's mad-scientist intelligence. But I'm wondering if he has what takes to show the Doctor's dark side which has been a common personality trait of the Doctor's for some time. Some of the other Doctors were able to do it chillingly without ruining the audience's sympathy for them. What are you guys' thoughts on this?
