Another great story that shows off Mel a she should have been and the Sixth Doctor as he was meant to become. He's still cranky and conceited, but he's re-learned his manners, which comes in handy when he lands in the middle of a spaceport that's been "quarantined" for so long that its inhabitants have degenerated into a pair of warring tribes -- and are bring stalked by something big, angry and scary. Quite a lot of fun. ( )
