Rebirth of Mothra II is an exciting and sometimes scary movie. It's also a lot of fun.
The special effects looked awesome. Toho did a very good job with the look of the movie. Most of the movie takes place out at sea, which is different for a Toho monster movie.
Rebirth of Mothra II starts off not too long after the last movie. Again the main characters are kids, with the bad guys being two adults (a couple of hunters). The evil fairy (and Elias sister), Belvera, makes the hunters obey her as she shocks them with her robot drone.
There are two monsters in this movie - Mothra (who is Rainbow Mothra at first, and then becomes Aqua Mothra later on for a sea battle), and the new monster, Dagarla, a sea monster. Their battle lasts half the movie.
There are parts of the movie that are similar to the Indiana Jones movies as the kids - Yuri and two boys - find themselves in a lost city out on the ocean. They find a room with what they believe is hidden treasure, but the treasure turns out to be something different. There is a hologram of the city's queen (who is no longer alive) and she tells the kids what the treasure really is.
There is also another creature in the movie, a cute little puffball named Gorgo that has more power than he seems to have. The battles in the movie are very exciting.
The picture quality on the DVD is very good and the double feature with Rebirth of Mothra 1 is recommended.
