Sequels usually don't work, especially in a show composed of serials, but this one is much more interesting than the previous one. The first serial with the Mara (Kinda) plodded along and didn't do much to capture the imagination (outside of the scenes where Tegan was talking with the Mara and trying to decide if she was real or not), but this one had a much more complex and interesting plot. And at least they didn't try the same effect of the fake rubber snake again!
