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.

The storyline feels a little thin and moth-eaten in parts but this sequel is plenty of fun.

Strong acting helps the film overcome an uncertain premise and create characters that hold our attention absolutely.
