I recommend this story and DVD to all Doctor Who fans. Very few stories still exist with Patrck Troughton as the 2nd Doctor.The story has the obvious cybermen in it but they are not the main villians,humans are,which is a nice twist well thought out. The effects are not up today's but that only adds to the charm. Since it is in black and white you really just end up enjoying a nostalgic reminder of 60's T.V.
