He wrote Rise of the Cybermen in 2006 which, while it features the shitty Parallel Cybermen and kind of rips off Spare Parts it was still pretty decent, definitely one of the less stinkier pieces of corn in the massive turd that was Series 2. He also wrote The Girl Who Waited in 2011 which, while Amy is a bit of a stuck up bitch to be pissed at the fact that she only had to wait 36 years while her hubby sat through 2000, it was the last time either of them seemed to have character development and it's the only good episode in the second half of Series 6 (no, fuck you, The God Complex was horseshit).
