I really love Tomb of the Cybermen. It's a fun tomb raider mystery gone very wrong. Funny enough, stories like this one usually are some of my personal favourites (The Face of Evil, The Satan Pit, The Pandorica Opens or Time of Angels, only to name a few... I even enjoy the most recent Ghost Monument for the same reason and more). The kind of story you'd see River or Bernice Summerfield involved. It's just somewhat uncommon coming across these, I think it's a bit more common to find the "base under siege" sort of stories, mostly because it's sci-fi and the tombs are usually pods/arks in space, which is also great in its own way.
I wondered what it was for a few seconds. As soon as I heard the Archaeologist's voice I knew what it was. I just watched the DVD yesterday. It was well done.
