We may both rag on the silliness and threadbare stories in this show, particularly in this episode — but I don't need any more detail on Jack Harkness turning into a giant head in a fish tank. You die and revive enough times, that's the end result 🤣

I think that's the sort of gaps that could never be filled satisfactorily on screen. They're much better as a space where viewers' imaginations roam wild instead.
