For InVision I wrote a piece suggesting what might have happened if Warriors and Androzani had swapped. Overlight Androzani, dark and moody Warriors.Warriors of the Deep was a good story let down by poor design choices (Rentaghost Myrka) bad lighting (all of them all the time) and either bad direction or bad acting (kung fu as though it was developed in a Surrey disco) but is otherwise decent enough hard SF than can only really be done in the Who setting (for the Silurians and Sea Devils as a third party race in the Cold War.)
Like Frontios, it makes a better book than TV outing. (Though Frontios would have been far far too grim if it had made it to screen with it ideas in place) Kinda would also be, but the performances and some of the weird stuff elevated it above Studio Jungle and Blue Peter Giant Robot Suit stuff.
