Remembrance of the Daleks is one of my favourite serials of all time. It's an excellent story, packed full of great and exciting action sequences. I love how it develops the character of the Doctor, making him more mysterious and manipulative. The other characters are also great, and I like the sets. I'm also a big fan of the score. The story also has some nice social commentary, for instance demonstrating some of the realities of the 60s. Overall, this is just an excellent story.
