...all those people gathered on the boat at the end. And our Guy and Cat. And they were like: "We are saved. Phew".
And it was funny since we know from other movies that there is a whole full apocalypse weeks from invasion. Only very few people like that Family survived. All cities fell. Everyone died. And 99% that all those people on the boat including our Guy and Car will die very soon. Probably like
next day or two. Since it looks in Quiet Place 1 and 2 that Monsters took over earth very fast and only few survived.
