Reviewers and viewers generally agree that the emotional gravity of the piece makes up for its structural flaws:

: The film masterfully weaves together real-time cellphone videos and photos taken by tourists right before and during the blast.

: Viewers looking to understand the geology or the specific vulcanology mechanics behind the surprise blast will find the explanations oversimplified.

If you are looking for a deep, investigative dive into tourism liabilities or geological science, this is not that film. However, if you want an incredibly intense, emotional, and visually staggering look at human survival and community bravery, it is an absolute must-watch.
