On one side, you've got a giant monster invading Japan; on the other Japanese government officials talking scientific gibberish and helping in no way the evolution of the plot. Godzilla Raids Again uses a format similar to the original, re-introducing a romantic side story for us to care on a human perspective, considering the rest of the film is cold, distant and deliciously apocalyptic.
As was the case in the first film, you get full-on action and plenty of monster footage. The novelty is that Godzilla finds an enemy his size; a new dinosaur there to project our aggressiveness in a somewhat safer place. The bigger-than-life titan fights add a new dimension in sci-fi. Having the beasts destroy themselves and man-made structure replicas is impossible to watch with a straight face.
The film looks great and the score is catchy. The performances took a drop and so did the screenwriting, at the expense of eye-candy. Leaving a dark past behind, this sequel offers you the fun rendition of a legendary concept that begs to be developed. Deep inside, you know you're watching men in rubber suits wrestling, but the illusion is so grabbing that you somehow accept it.
