3) Rebirth of Mothra I- Good solid Kaiju action, but the story was pretty kiddie movie-ish (it might even be a kid's film, I have not researched them yet). Very high "Kenny Factor" and the kid's voice dubbing was painful. I still have II and III to at least speed-watch.
They are kids movies, and ehhh they're okay I guess. The 3rd one is pretty good.
