I like Stones but it's the last in a long line of Gothic horrors whereas Tara is trying something new, which will always get points from me.

One thing I will say about Stones: it's arguably the most female-dominated story in the canon: aside from the Doctor, there are only two male characters, compared with four female ones (counting Romana). Of the male characters, one dies some time before the halfway mark, the other has about half a dozen lines (and also dies). However, the robots do all have male voices.
