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.
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 :(
