For me this is one of the worst stories in all of Doctor Who. There are a number of problems with this episode. But, one of the main reasons I dislike this more than almost every other DW story is because it commits the unthinkable crime of being boring. Really, really boring.

There are other reasons I don't like it though.

I don't like criticising child actors, but so much of this episode relies on Chloe Webber working as a character, and unfortunately the performance is not good enough. To be fair to the actor though, it's not a very well written character. I'm not sure Meryl Streep could find a way to make this character interesting.

I also dislike the stuff with the dead father. I get that just having a child with some colouring pencils be your antagonist isn't very threatening. So I understand why they had her dead dad, who was abusive before his death, coming back to life from his picture. But it's just a red light and an angry voice. It's such a boring monster. The justification for this even being a thing is that if living things can become a drawing, then drawings can become living things. I appreciate a red light is very cheap, but Chloe could've drawn anything. Surely they could've had Chloe draw something that was a little more interesting and still cheap. Hell they could've kept the red light and still written out the abusive dad.

I dislike the child abuse implications in the episode. Especially because the abuse angle feels very tacked on. There's no reason for it to be in the episode. It's never explained or explored, it's just a lazy attempt to add some drama. The closest the episode comes to given a reason for it's existence is because the plot requires Chloe to be lonely. An abusive dad can likely explain why Chloe liked to sit on her own drawing. But the episode makes more effort to explain her loneliness is because her mother isn't there for her. If you've got a dead dad and a neglectful mother, that's more than enough reason for Chloe to be lonely, you don't then also need to make the dead dad an abuser. I think throwing in past trauma without any real justification is a very cheap way to create drama and tension. It's made even more unforgivable here because it fails to create any real drama or tension.

And the less said about the 2012 Olympics stuff the better. It's some of the corniest writing in the entire series. Apparently the olympic torch is humanity's greatest symbol for hope and love. So much so that humanity is seemingly about to give up on both those concepts when the torch bearer collapses. But luckily the Doctor is there to carry the torch and light the olympic flame, and our hearts or something. Yuck.
