An interesting early Doctor Who story but the action revolves around overcoming obstacles due to size rather than facing monsters. Originally scripted as a four part story, episode 3 and 4 were condensed into one episode before transmission. This condensing created plot holes but this release includes an extra that presents episodes 3 and 4 as intended. The episodes were created using very basic re-editing, animation and dubbing but they resolve the plot holes. This story is best for dedicated fans rather than dabblers in Doctor Who.
