matt lynch’s review published on Letterboxd :
ill-advised genetic tampering is the stand-in here for nuclear annihilation, but it feels entirely arbitrary. the big guy's analog is too specific, you can't just make him a metaphor for whatever given technological bogeyman is in fashion.
Honda's wide open frames or Fukuda's crammed compositions are missed too, especially in the otherwise impressive final battle. the camera is mostly fixed and frequently in close up (probably because the animatronic monsters aren't very mobile), even while the miniature FX in these get more elaborate and more stylized. Biollante is like a kaiju Audrey II from LITTLE SHOP OF HORRORS, but her appearances are few and far between. most of this is constant expository yammering from the human cast, made all the more interminable at a bloated 105 minutes.
