Well, if you've already seen the original broadcasts then you will already be wise to the three episodes (7, 8 and 9 ). This is half-way through the series. Personally I like the darkness of Amy's Choice and its denouement and the foretelling the demise of one of the main characters. Toby Jones gives a wonderful performance as the menacing Dream Lord? But Who is he?
The Silurian story ( The Hungry Earth, Cold Blood) might give the Silurians more depth and complexity than previous incarnations, maybe humanising them a bit too much in my view, but even Silurians involve, I suppose! Myra Syral is very good as the geophysicist and her ending unexpected!
If you buy all the new series DVDs as released as I do then you will already have bought or about to buy it. Amy's Choice is definitely better than the Silurian episodes. I'm sure some Dr. Who fans appreciate some stories more than others.
Make up your own mind!
