HARRY SULLIVAN IS AN IMBECILE!

To be honest this story takes a while to really get going, the first 3 parts are kind of boring after the opening. The Cybermen look cool in this episode, especially with the head mounted weapons, but the voices are abysmally bad, like they did not even try to make it sound robotic or computerized in any way

The scene where the Doctor steers the beacon away from colliding was very well done though, the effects in this episode are pretty decent
