I should have expected it, I guess, but I was still surprised when the mathematician (the token woman) brought everybody sandwiches and coffee before the final flight.
1000 Misspent Hours likes it:
what makes The Giant Claw truly special, beyond its ludicrously inept dialogue, its impressive misuse of stock footage and voiceover narration, and its legendarily cheap and unconvincing special effects, is that it boldly defies the aforementioned pattern. The Giant Claw is every bit as unrepentantly bizarre as any Japanese or Korean creature film, and in exactly the same characteristic way. It is, so far as I’ve seen, the only true American kaiju movie.
StompTokyo talks about the Alien bird:
What makes The Giant Claw a schlock fan favorite, however, is the monster. And oh, what a monster – part vulture, part Looney Tunes Dodo, and all puppet, the Giant Claw glares at us with its googly eyes, flares the nostrils on its mushy beak(!), and mocks us with its shock of black hair....You will recoil in horror – that is, if you can keep from doubling over with laughter.
BadMovies.org has a thorough plot description, sound and video files and this: "It is impossible not to laugh about the movie's special effects."
