It's wrapped up in style.

More nightmares for Mary Whitehouse, as The Brain of Morbius concludes, it's a deliciously dark final episode. The Doctor battles Solon, Morbius, and has had to contend with the powerful Sisterhood of Karn. It's blatant that this story was a homage to Mary Shelley's Frankenstein, and just as we saw in many of the films, the showdown sees the Monster on his feet, terrorising all those who stand in his way.

As I've watched, I've been struck by just how visual this story has been, clearly there was a huge focus on attention to detail, and ensuring this production looked very good, it's helped by excellent lighting, great costumes and wonderful sets.

I loved the performances throughout, a special mention for Philip Madoc, he didn't at any stage go over the top or play for laughs. The laughs definitely come from Baker, the episode concludes with a nice, humorous line from Ohica.

The Sisterhood were a terrific creation, I was so glad to see their return in New Who.

Part 4 is excellent, overall I'd say it's been an excellent, consistent, well paced, entertaining four part serial. 9/10
