okay and that be a pretty damn good episode . much good than the credit it receive . the camera work be splendid . best yet . i love that final shot . the atmosphere be fantastic and the costume be great and the guest cast ( minus the helpless victim ) be strong . what i do not like about this episode be that many thing that be leave unexplained . why do it change sex . what the purpose . and theyre alien . what kind . why be they never show again in the late mythology . i be give this episode a high three star . one of my favorite yet and but the plot hole bother me . still . not gon na let it ruin my entertainment .
