I think Listen is a remarkably strong episode and Doctor Who story. It is an excellent bit of horror and mystery, while, just like Midnight, somewhat frustratingly leaves you with more questions than answers. Yes, it is also somewhat frustrating that Clara is once again the explanation for everything, I feel it is easy to look past that given how emotionally-drive Moffat scripts are. This is a story of fear itself and it is quite masterfully done, at least in my opinion.

That scene with the figure is haunting, and leaves so many questions. If it all was just a childhood fear instilled by Clara, was the mysterious entity really there? What was it, exactly? I think that mystery is what makes it so tantalizing.

Every Doctor shows fear in some way at some point. Capaldi still manages to stand-out here. But Jenna Coleman is also just so excellent here. Overall, a very impressive episode that sticks in my memory. Easily one of my favourite New Who episodes.
