RTD did not write Father's Day, did he?

No it was Paul Cornell's episode. But RTD might have asked for that line. As he asked for some of the jokes in Fires Of Pompeii

But I believe that line was used earlier in an RTD script. I might be wrong.

See, that doesn't surprise me at all. The episode was nigh-on perfect, but just a few things smacked of RTD. He really needs to GTFO and stop screwing with other people's work.

The line I was referring to was from "Rose".

Oh I don't remember that.

That's what I thought.

I thought it was OK (5/10), but this was a very weak start to the new season. There was so much that could've been done, e.g. focusing more on the body horror aspects of the Adipose and make them a little more creepy but still keeping that surreal dissonance.
