Decent concept for a story, definitely one I could see working in Doctor Who as well. It was interesting enough and we got some mentions of the Doctor. Honestly, not all that much to say about it

It was a genius idea revolving an alien menace around the ancient suspicions of astrology. Plenty of recognisable folklore for Gareth Roberts to tap into. The idea of a washed up astrology reader gaining real powers and taking over the world is delicious. Two stories in and this gang of Rani, Luke, Clyde and Sarah-Jane feel iconic. The show has reached its ultimate form. The only quibble I have with this story is that it's another mass-hypnosis number, but to be fair, it's carried off far better than The Christmas Invasion.
