There's no use in avoiding this movie like the plague(which, admittedly, I do), yeah it's the Black Sheep of the Godzilla series, but in all honestly it's not that terrible. It's like a Showa Gamera film, watch it, but don't expect anything out of it except pure cheesiness.
This is my least favorite Godzilla film, horrible, putrid(am I contradicting everything I just said?) with so much stock footage it's unbearable. Watch it if you must, heck, even like it if you must. It's worth watching, even if it's just so you can say 'I've seen 'em all.'
Sorry if I was too hard on it.
