My Doctor Who journey is continuing and I've gotten about halfway through series four, which sadly is David Tennant's last series. I watched "The Unicorn and The Wasp" last night, and I loved the Agatha Christie plot line. I read all of her books when I was in 6th grade and I would love to go back and reread them at some point. This is my favorite scene so far in this series, and maybe in show so far. I just love Catherine Tate to pieces. I hated Martha so damn much, seriously I feel bad because I spent two weeks whining to my friend Andrew every day about how much I hated her. Sorry Andrew. But here's a taste of why I'm going to miss Tennant and Tate when I have to move on to series five.
