While she's clearly been let down by the material, she wasn't able to elevate it the same way Peter Capaldi could. It'd have been interesting to see her under a different showrunner, but I guess we're getting second best, which is a different Doctor under Chibbers...
funny if Kris Marshall really did become the Doctor this time
It'd be cool if John Bishop is a "stealth cast", be it through Chameleon Arc or something.
