This is a must-see and one of the best documentaries - and films - of this year.

If you like to be scared, if you like to laugh, and if you like to learn a thing or two at the movies, this absolutely cannot be missed.

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.
