How did they ever survive in the first place?

Rating: 3/10 (2 August 2018)

A family of idiots make all kinds of stupid mistakes during the span of the movie that one can only wonder how they managed to survive in the first place. At the end, a lot of questions remain unanswered (mentioning the questions would be a multi-spoiler), probably because this the only way for the story to make any sense at all.
