The ugly side of New Earth
13 February 2017 | by See all my reviews

"Gridlock" is the third episode in the rebooted show's third season, and it's certainly one worth watching. It satisfies on a narrative level, but also on a visual one, with the show's creators presenting the vivid dystopia of New Earth (a place familiar to most fans). We see the relationship between the Doctor and Martha develop rather substantially in 'Gridlock', largely due to the situation in which they each find themselves: early in the episode, Martha is kidnapped, and we can plainly see the Doctor's desperation and anger at having lost a second companion so soon. One of the more interesting supporting characters, the Face of Boe, also makes a significant contribution to the story of this episode. Keeping his promise, the ancient sagely alien finds himself in the company of the Doctor one more time, and in doing so he delivers perhaps the most intriguing scene in the episode, revealing something to the Time Lord which will excite the curiosity of many fans. If some of the other supporting characters were written with the same level of imagination used in the creation of New New York (the city in which this episode is set), this would most likely rank among my favourite episodes. Still, this omission doesn't detract from the episode too significantly, and I feel my 8/10 rating is well-deserved.
