The reference to The Web of Fear being set in 1975 means that Colonel Lethbridge Stewart retired before he became a Brigadier and joined UNIT!!! The Invasion took place a couple of years after the events in the underground.
Why didn't Moffat simply set Web of Fear in the year it was made? (1968).
The opening titles were cheap and nasty. Not much improvement with the theme tune, which changed 4 times in the first 5 years.
The comedy turns were terrible.
The TARDIS interior looked like a kids play set (perhaps a Christmas toy for next year?)
