It has that exact right combination of seriousness and absurdity and body horror and science fiction that is Dr Who. They nailed it.
That whole entirely unnecessary gravity bit, ridiculous and absurd, but funny.
Donna almost getting left behind, the captain commiting fucking suicide shows the seriousness of the episode.
I just loved it.
I had the same thought. They’re in the mavity universe/timeline right now, and somehow righting things back to gravity is going to also reset the flux stuff so that half the flipping universe isn’t destroyed. RTD likes to clean up messes if I remember correctly (I’m not the super fan some are, so I might be misremembering?), like how in the star beast the roads somehow repaired themselves after cracking open. I think he’s setting it up to clean up the aftermath of Flux.
But, resetting things will also mean that Donna is set back to being in danger if she remembers stuff. He’ll have to make the tough decision that fixes the universe, but dooms his friendship with Donna once more. It’s RTD’s style.
Oh fuck, you’re right. Now my heart hurts all over again :(
