A decent first half of the finale. I loved the 10ft centipede police guy, he's a fun character. Not a fan of the Sisterhood of Karn, so that's a negative in my book, but overall I think it was a decent story. Have not seen the episode that this is a sequel of, so I'm a bit confused.

This one's a lot of fun. Lucie is alone, separated from the Doctor and completely out of her depth. Luckily, a giant centipede, played by the wonderful Alexander Siddig, is here to help her out.

The story focuses mostly on Lucie as our protagonist, and her characterization here is fun. She gets to make some mistakes and learn from them, and we get a rare glimpse into a more serious side of the character. Miller and Siddig have great chemistry, and Rosto's a fun character in his own right. We have the return of Nikolas Grace as Straxus, and he's as smarmy as ever. There are some great back-and-forths with him and Lucie, arguing like petty children. Zarodnix is a pretty thin villain and only really exists as a way of getting the real baddie into the picture. Kenneth Colley does a really good job regardless.

The Eighth Doctor's side of the story is fine. He deals with the Sisterhood of Karn (coincidentally, he'd meet them again in Night of the Doctor on TV) and they're basically there to answer his questions and provide another Morbius connection. They get a bit more to do in the next story. I will say that Katarina Olsson isn't great as the leader of the Sisterhood. Her attempt to do a wise old lady voice is pretty silly, and the fact Olsson is already in a much more prominent role in this range (the Headhunter) just makes the whole thing distracting.

Overall, really fun first part of the story. Lucie is at her best and really shines here.
