Utter drivel; just ask one question to yourselves ' how did the power all the electrics in the house, bunker, war cctv and computer suite the outside seaside lighting etc etc etc'? I saw not one windmill (which the aliens would have destroyed because it made a noise), not one solar panel, not one mini hydroelectric generator on the river and no noisy petrol or diesel generated generator.
I could destroy the practicalities of their existence non stop; why in the chemist not take all the drugs available not just the one they came fir, why burn 20 candles at once in a room when only one is needed?
I could write pages and explain how the film actually sends any thinking person up the wall with its implausability at evry level.
I must stop now as I'm now watching the second film to see if it can be as implausible I'm guessing it's going to be much, much worse lol.
