The Flying (Teenage?) Mutant (Ninja?) Turtle!
10 October 2006 | by (the Draconian Swamp of Unholy Souls) – See all my reviews

What's that there in the skies? Is it a plane? Is it Superman?? Errr, no… It's a TURTLE!?! See, that's what becomes of the Cold War! Nothing but bad news and other issues! The Americans shoot down a Russian combat plane somewhere over Artic territory and the subsequent explosion defrosts & literally awakens the giant prehistoric turtle-creature named Gammera. He/she is not a very friendly critter as it promptly ensues to destroy everything and everyone on its path. The arguing governments finally decide to kill the ugly bastard with a brand new and super-sophisticated ice-bomb, but Gammera has another surprise in store… The damn turtle can fly! The first time this happens results in a tremendously grotesque and hilarious sequence! Gammera lies on his back looking defeated when suddenly fire blows from his armpits and he skyrockets himself up in the air. How can you not love that? Then there's also a dire sub plot about an annoying kid who's able to telepathically communicate with the monster, but that's just not interesting enough. Flying turtle, people!! There's very little else to write about this Japanese (and American re-edited) Sci-Fi effort, apart from that it's an obvious and totally shameless rip-off of such classics like the original Godzilla and The Beast from 20.000 Fathoms. The effects and monster designs are extremely hokey and, unlike the aforementioned films, it never succeeds in creating an apocalyptic ambiance. Respectable actors like Brian Donlevy ("The Quatermass Experiment") and Dick O'Neill ("Wolfen") seem unaware of what film set they're on and even the original Japanese mayhem-scenes aren't very convincing. Gammera's very own and personalized theme-song is rather cool, though, so it gets one extra point for that.
