Doctor Who and the Silurians - Episode 2

OK, a bit of a cheat on the cliffhanger resolution. The dino gets called away by a weird signal thing. We do get to hear the Silurians, and also kinda see one, or at least part of one. The shots of the wounded Silurian, especially its POV, are very well done, very effective. Avon from Blake's 7, Paul Darrow, makes his first Who appearance here, as a UNIT officer. All in all, this episode seemed to be marking time, aside from the wounding of the Silurian. Decent, but not gripping.
