Things I learned from watching The Invaders
1. David Vincent is not a practising architect and has visible means of financial support. His business partner was killed off in episode two. David never has anything to do with architecture practice except one episode 'the innocents' when he briefly admires a building. but apparently that was only in a dream
2. Hot women seem to hang around where there are a lots of aliens
3. Everybody seems to drive Fords and there never many European cars or V8s
4. The 1960s American and British pop music culture seem to have bypassed the invaders. The only music playing on jukeboxes in the invaders is crappy Muzak
5. Aliens from advanced civilisation can travel great distances between galaxies but they still have analog controls in their space vehicles
6. The aliens are real smart but not wise enough to just shoot David Vincent dead.
