Jodie Whittaker is the WORST Doctor Who
Whittaker is the worst simply for bad acting, apeing 10's and 11's styles with having no discernible identity of her own, and just generally cringe expressions a lot of the time, and the rainbow stripe costume does her no favours.
Colin Baker used to get the shaft for bad acting and bad costume, but I'd say that he is a Shakespearean-class actor next to her, especially with his Big Finish redemption.
