Title: A time travelling mess!
Review: The Keys of Marinus is a good example of what can go wrong with a new series. Doctor Who was in its infancy, it's first year to be exact. The Keys of Marinus dealt with a series of stories within the story. The Doctor and his companions arrive on Marinus and find they can only leave if they help the keeper of a powerful artifact recover a number of keys that can activate it. The problem is the keys are scattered throughout the planet. The four are given travel watches that transport them to each of the keys locations and thus adventure ensues. The problem is the adventures are boring for the most part. Keys of Marinus us only for the diehard fan.
