Don’t Blink.
Hands down, scariest episode EVER!!

Even watching it over it’s still scary.
The effects, the music, the fear of something that won’t move while you are looking.

This was the most amazing episode ever..

On top of that, it wasn’t an episode that truly starred the Doctor. All shows have them, episodes where the main characters have a small part, as if they were on holiday or something.

This episode beats every single one of them hands down. It’s brilliant and scary and delightful and terrifying and intense.
