Rise of the Cybermen is the fifth episode in Series 2, written by Tom MacRae and Russell T. Davies.
10, Rose and Mickey land in alternate London. Rose is an idiot and goes to see her father again after killing The Doctor last time she tried and the Cybermen make their first appearance in NuWho.
It's a "Russell T. Davies does tons of rewrites" episode. It's shit.
The lasting and terrible legacy of the episode is that the Cybermen were brought back at all, tragically.
It's no Spare Parts.
