Gamera 3: Revenge of Iris (1999)

The final entry in the Heisei era Gamera trilogy is the best of the lot. Of course there’s kaijū fights, but even better is the story. It explores, from the perspective of one orphaned girl, what it means to have been in the thick of the action during GOTU (1995) and watched everything you love be destroyed: the cold and callous name for which is collateral damage.
The visible enemy resembles something from a JRPG. There’s tentacles that admittedly would be more challenging (however not impossible) to do without CGI, but I wish they’d been less liberal with it elsewhere, because it's the only stain on an otherwise astonishing display of super-detailed models and guys in rubber suits being awesome.
