An action-adventure yarn wrapped around a monster-movie core, Ragnarok elevates familiar B-movie material with well-matched cultural specificity and realistic family dynamics.

"Ragnarok" is the rare Spielberg clone that feels like it was made by people that not only know what they like about Spielberg's films, but are capable of evoking them.

In the end, any and all potential B-movie fun is extinguished by Ragnarok's depressingly listless anonymity.

Successfully delivers a family-friendly adventure akin to Amblin outings from the '80s, while also injecting some fresh perspectives by delivering a blend of H.P. Lovecraft and Viking mythology.
