Well, why did we need three "Rebirth of Mothra" movies with a year in between one another? Seems a bit excessive and cashing in on the success of the Kaiju genre.
Regardless, I sat down to watch the 1997 movie "Mosura 2: Kaitei no deikessen" (aka "Rebirth of Mothra 2", just shortly after I had sat down to watch the 1996 movie "Rebirth of Mothra". Wait... Something is amiss here. The two movies were almost clones of one another, just with minor changes to them.
In both movies, Mothra is reawakened to come to fight another Kaiju that has been stirred from its slumber. First it was a three-headed reptile, then it was a winged aquatic reptile. Two miniature women ride around on a miniature Mothra and calls forth Mothra from her sleep. A group of children are drawn into the fight against their own wishes.
Yup, the 1997 movie was essentially just a clone of the 1996 movie. And that was a shame. Whereas I enjoyed the 1996 movie, seeing everything again just with a different enemy, different children, and such, didn't really do much to win me over.
That being said, if you haven't seen the 1996 "Rebirth of Mothra" movie, then you will definitely like "Rebirth of Mothra 2" - as they are essentially the same movie. But for us that have seen the previous movie, this was a bit of a shallow cash-in.
But wait, in this 1997 movie Mothra becomes fully submerged in salt water. One would think that a moth and salt water is not the best of combos. But I guess a Kaiju moth is impervious to that and survives it regardless.
There are minor changes between the 1997 and 1996 movie, but not enough to really make the two movies different. A shame really.
