Sadly, this is the kind of casting I was hoping Doctor Who had stopped wasting time with.
At least Gambon is an actual actor, I suppose, even if he is an arrogant jerk, but Jenkins is just an annoying singer. I wish we could go back to the days when actors auditioned for parts.
Who is to say she didn't? And I don't find her annoying at all.
Also, do the math - they brought in Kylie and got one of the highest ratings in the show's 47-year history. Jenkins has recently launched the American phase of her career and only a few days ago had a huge profile done on her on CNN. Which means as more major media pick up on her, there's more chance the profiles will now included "soon to appear on BBC America's Doctor Who."
Don't be elitist. As far as I'm concerned they can bring in Lindsay Lohan, Britney Spears, Kim Kardashian, Kate Gosselin AND Graham Norton for all I care. If the story is good and they do a good job, why should any of us give a s*it? I'm not a huge Kylie fan but I loved her Astrid Peth and I'd cheer for her return in a heartbeat.
Just remember that every time time this sort of "annoying" casting happens it's simply more proof that Doctor Who is continued to be held in high regard. Hell, if they want to pull the Batman thing and have a celebrity cameo in every episode I'm fine with that if Moffat can find a way for it to work.
