Here's a review of Godzilla vs. Gigan, courtesy of my 11-year-old, Ian:
Godzilla vs. Gigan is a decent kaiju movie complete with giant monsters flailing around. In the movie, cockroaches invade earth using the alien dragon King Ghidorah, and the cyborg Gigan. Gigan has a chainsaw in his belly and resembles a chicken. Godzilla and his sidekick Anguirus come and save the day. The movie, however, is very cheap.
They keep using stock footage, so the scenes are always changing from night to day (I could see Larval Mothra for a split second in one scene). But, who cares? Not me. The action is great, but a major annoyance throughout the movie was the fact that the movie had soooooo much talking. It was annoying to have to constantly fast forward through all the talking in order to see the action. But, go ahead and rent it. Even if it is annoying to constantly fast forward or watch all the talking, it's still worth the giant monster fight scenes.
