I personally feel I can emotionally connect to this film due to the allegorical theme (the whole Godzilla series runs on allegories, for those who don’t know), but not how the theme itself is executed due to the behaviorisms of some of the characters.
ESPECIALLY the main kid. It does depend on how you see his character, though.
If you just adore the baby kaiju Minilla (originally from ‘Son of Godzilla’, 1967) and want to see what other shenanigans he’s been up to in the original Godzilla series, go ahead and watch.
