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.
Donna is both my least and most favorite character. It’s interesting. I hate the character when she’s being overly critical and hostile for no reason, which she was mostly in the beginning (and still is a bit, here and there), but her character development is the best in the series. She’s one of the most caring and empathetic characters that we’ve seen so far and I love that. And her (previously) final arc was absolutely heart breaking.
That’s the thing about humans. They can hold two opposing ideas in their head simultaneously.
