A well-oiled concept!
This is the third Godzilla film to feature robots as fighting inventions and it may very well be the most successful at it. Mechagodzilla is a remote controlled metal version of Godzilla. Pulling levers and pushing buttons behind it is a bunch of oddly assorted gangsters; cultists perhaps. This is the underlying mystery that leads us to yet another battle of behemoths.
The photographic evolution of the franchise has been slow but steady. Godzilla vs. Mechagodzilla is one of the best looking ones. This said, it constitutes nothing more than the background story of a monster we barely get to see. Robotics, space travel, prophecies and general occult references are used in the plot and it’s a nice, fresh combination.
Sadly, this is another one that keeps the best for last, leaving a gaping hole in the middle act for anyone desperately seeking kaiju mayhem. The adventure genre works here because the human protagonists need some connection to the monster, but the whole spy and conspiracy subplot comes out as tired filler. While the movie is entertaining, it feels like two stories in one.
