From TEIN? About Dr Who? I don't believe it.Slight criticism follows (sorry)
You do have a point, especially as there was a whole planet contained inside the thing, and the Earth was going to be next. I made her seem very blase.To make things worse she then straps grenades to a device she knows nothing about (other than blowing it up could cause mass destruction) and off she goes to do the very thing she slapped Graham's wrists about not five minutes earlier.
I'm not sure I followed everything this week, so I'm sure the younger audience wouldn't have, but if this was to satisfy the elements that want more science fiction and less historical drama, then I hope it sufficed. For me, this is more fantasy than science fiction, or at the very least, space opera.
