Was?
You literally haven't sen ANYTHING he has done and you are already done.
Not much of a chance you gave him, relying purely on rumor.
If the rumor ends up being wrong, I'll give it a fair shot. But, if the rumor is true then that's it. I'll be hate watching, but there is zero chance that the shit in that rumor won't be the worst thing to happen to the franchise. The bad thing is that it will also hurt to have the first female Doctor's debut series be complete shit.
I'll hope the rumor is wrong, and if it is he has a good chance of doing something good. But if its right, obviously he's just took a giant crap on the franchise. That premise doesn't work, period. Until the rumor gets confirmed or denied, it could go either way. I'm just saying that if it does go the bad way, and Chibnail is someone I can see doing something this shit, then the show is royally screwed and he'll be the worst showrunner/producer the franchise has had (outside of possibly Cartmel, although even his era had one or two decent stories mostly by accident).
As for people who don't like this idea, just remind yourself that this will be just for one season.
"Just for one season" is a BS excuse when Doctor Who has few episodes per season and a huge amount of time between seasons. Its not like a lot of shows in the US that run for 22-ish weeks (with an off air month in the middle, usually) and have, what, half a year in between seasons? This is a show that will randomly take a year off because it can. Its like if Sherlock had a series where Benedict Cumberbatch was playing Sherlock going to clown school and solving only one case (at the clown school) over the three episodes. Even if its just one season of crap, when the show is rarely on its a big issue.
