Starts with an interesting premise, where the Doctor and company seem to have slipped into a sidestream of time, when they land in a Space Museum, but cannot be seen or heard, but can observe.  They find themselves and the Tardis as exhibits. Eventually, the time sidestream joins back and they become part of a more conventional adventure and become in a power struggle between the ruling Moroks and the enslaved Xerons.  The entire series ends with an interesting conclusion – the daleks are hunting them through time.
Rating: Good 5/10
