I find it really hard to talk about this serial. It's just kinda dull. The Sontaran is dull, the humans are dull, even The Doctor and his companions are kinda dull. The biggest thing I can remember thinking when watching it was how incredibly padded out it was, despite being far shorter in episodes (2) compared to the usual fare for these serials (4). I give this serial 1 1/2 stars, or the rating of, "A Blue Boringer." Laters.
