Sylvia comes to the rescue with an axe, but would the Doctor have been so dim??
Toxic gas is pouring out of the cars, and the (small) Sontarans are preparing for war. The Doctor accuses them of cowardliness and learns their ongoing war with the Rutans is going badly. Martha's double is proving a thorn in the side. The Sontarans invade the base (at last,) but UNIT retaliates. The Doctor discovers what the gas is and sets about putting it right.
The Sontaran ship is a fantastic design, I liked the Sontaran invasion, the music was good. I loved the brig mention too.
I wasn't overwhelmed with Part 1, but it did have a few small redeeming features, The Poison Sky doesn't have too many, the performances are great in general, but the script is dreadful.
Are we due an episode with the Rutans? would be good to have a re imagining of them.
I will forever remember 'back of the neck,' loved Donna clubbing the Sontaran.
Is it a total disaster? not quite, there are some nice bits, the battle scenes are well played out, some of the effects are great, I quite like the Sontarans, they are well realised, other then that it's lacking on so many levels, all really due to the bad script, the actors gave their best, but poor 4/10
