Such an unusual series. Putatively about an alien invasion but it focuses on the characters so much it’s really about how they react to and deal with the events.
It has a strange “generic atmospheric sci-fi horror possibly-trying-too-hard-to-be-realistic” feeling to it ala Cloverfield etc, but it’s also fairly unique in that the characterisation is REALLY deep and believable. I was sad when Casp went into the coma
The comparisons to The War of the Worlds are pretty obvious. It also reminds me sometimes of a sci-fi novel series called The War Against the Chtorr
