There is no doubt, here. This final entry in the early Gamera series is dreadfully painful to watch, for any age (oh, maybe a two-year old would like it). This sick joke of a movie has laughable effects (was that done on purpose?), indescribably stupid dialog, atrocious dubbing, children you want to see lose their voices and/or disappear (annoying just doesn't cut it), a done-to-death plot, and maybe some other insults to intelligence I haven't listed here. Sure, it's a kiddies' movie, but WTF? At least add SOMETHING new or watchable (other than the ridiculous villain monster), film-makers. To call it fun or entertaining really strains these words' definitions. Egad, when Gamera does that dance... Even MST3K's riffing couldn't make this cinematic dreck funny or interesting, and THAT says it all, folks! Check out the late-nineties trilogy of Gamera films, instead. Now THOSE rock the house!!
