I've been trying to put my finger on why I haven't been enjoying the last few seasons, and I wonder if I'm just getting tired of it. Doctor Who is a show that will never have a "series" finale (As in, final episode and then it's done) and I've been watching this series for more than 10 years now. While I like Capaldi, and think he does a great job in the role, I find his doctor kinda arrogant and maybe even a little unlikable. Maybe like other people have been saying, it's the scripts and not the actor but I no longer find the joy of watching this series like I did. Like I said, maybe it's a commitment thing and this will be my final season.
For me the show seems to be losing its sense of identity and purpose. There's no growth, and there's nothing to tie anything together. As a rule, I don't have a problem with standalone stories, but I do have a problem with entire seasons that meander without actually going anywhere.
Part of the problem right now is Clara. I have actually enjoyed her as a companion, but she seems to keep being pushed farther into the background, and it's a bit off-putting. Even though I wasn't a huge fan of the Danny Pink storyline, it at least gave Clara something to do. In the Viking episode Clara admits that the Doctor is a hobby; well, I need their relationship to be more than that if I'm actually expected to care about it.
She's gone from The Impossible Girl to The Girl Who Tags Along When She Doesn't Have Anything Better To Do. It's boring.
And I think I would be able to forgive her lack of development if there was more going on with the Doctor himself. What about Gallifrey? WHY AREN'T YOU LOOKING FOR IT?!
People have mixed feelings about the River storyline, but at least it gave the Matt Smith years a sense of cohesion. Amy, Rory, River, and the Doctor became this weird, timey whimey family, and they all loved and cared about each other, and that in turn made me love and care about them.
I don't love Capaldi. I don't love Clara. I like the actors, and I think they do a good job with the material they're given, but I honestly don't care about what happens to them anymore because the stories are meaningless.
