This is one of the gushiest most ridiculously unrealistic depictions of an alien invasion ever made. I am sure the writer would say the focus of this film is on the people and the effect of an alien invasion. Scenes are painfully drawn out trying to make you care for the characters but thanks to poor script, story and acting you don't.
The only thing you care about is why the aliens are there and you hardly see them. It is also advertised with Sam Neil the only credible actor. He is in the first episode and then not seen again.
I should also add there are some terrible stereotypes.
Admittedly I am on episode 9 but not sure I can be bothered with the rest.
