Silly, childish, yet guiltily enjoyable at its best!
All Monsters Attack, AKA Godzilla's Revenge, was not so much a Godzilla movie as much as it was a greatest hits reel, the film was decidedly more childish, as it was the first G-movie intended for kids. The monsters aren't real in this one, they're part of a little boy's overactive imagination, which also explains why the ogre-like monster "Gabara" only appears here. Talking Minilla (or "Minya" for some) is definitely creepy, but in the end, the film's quite enjoyable, childish yes, but intentionally so.
This DVD release is digitally remastered, contains both English dub and original Japanese versions, as well as the Ishiro Honda biography featurette (a must-see for G-fans, definitely interesting!) I recommend if you're looking for this film on DVD, this release is the one you want!
