Great classic Dr Who
19 May 2007 | by drwordsmithSee all my reviews

This episode of Dr Who is again showing that this series is getting better, but taking its sweet time to get there. The episode is very reminiscent of the series 2 episodes "The Impossible Planet/The Satan Pit". The episode was fast paced and very scary in places, I can see why the BBC didn't want to put it on before 7 o clock. Like most of the episodes of Dr Who this series, and the last two for that matter, there was a lot of running around, but the episode was clever and surprisingly emotional as well. It also managed to overcome the 'episode 7 filler' syndrome, as these episodes tend to be the blandest ones in the whole series (the long game, the idiots lantern). All in all, a very well made, exciting and tense episode.
