To start, I have to say Mechagodzilla is amazing in this. From his design to his abilities he's just cool all around. He even poses a real threat to all of its opponents. The action was great though, specifically the first battle between Godzilla and Mechagodzilla caught my eyes and looked visually stunning especially for its time. Godzilla vs. Mechagodzillas story was okay, it felt fresh enough for me not to want to compare it too heavily to Invasion of Astro-Monster or Destroy All Monsters with its alien villains because it does bring in some interesting new concepts and depth that the others didn't have. The archeology / statue prophecy side of the story intrigued me at first, but kinda of lost me in the middle of the film and never really gripped me again. It even had some great memorable characters like Agent Nanbara, who if there was ever an Americanized verizon of this film, would definitely be played by Keanu Reeves. All in all I feel like this was yet another solid entry in the Showa era Godzilla universe with the introduction of Mechagodzilla along with a pretty decent story and some great action.
