Gamera is, as promised, back for his 50th anniversary. In his most eye-popping (and -melting) adventure yet. This looks like a touch of Gamera the Brave's structure, as well as Shûsuke Kaneko's plot. Gyaos, Gamera's most popular enemy, is back, and if you watch closely, you can see their breath weapon in the background.
Good for the director for having the foresight to introduce a new monster. This is hopefully a forward-looking entry into the franchise, not a backward-looking one.
