Hide was a great episode. Visually arresting and jammed full of interesting ideas.
It might sound weird but why couldn't the Doctor be stuck in 1974 now instead of back in 1974?
The look and feel of the clothing and the electrical equipment added a touch of The Stone Tape to the piece and the 'monster' was genuinely disturbing. All that was missing was an old style radiophonic soundtrack.
I can see a generation of kids looking back at this one in the same way I was freaked out by The Image Of The Fendahl.
