Although it has its amusing moments, in eneral the plot does not convince.

if their story seems completely bonkers, almost like a feverish work of fiction, you ain't heard nothing yet.

Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

There are moments that feel comical, some horrific, and some downright inspiring but the tonal shifts hardly matter as the end results come to a film that's perfect for this time.
