I don't like this story very much. I feel that Nyssa is completely out of character, as is the Doctor to some extent. I feel like the story is very weak as well.
I don't have the memories you do. I watched my first episode of Doctor Who in 2007, and my first episode of Classic Who in 2011. So maybe the idea of having new Who during the wilderness years, and the nostalgia of it all informs your opinion a lot more than mine. But yeah, not a fan of this one. Although I do agree having Peter Jurasik and India Fischer in it is great.
