This movie is like season 4 of this series.
Story is similar to hollywood movies where terrorists with knowledge and intricate planning try to do the impossible.
Though the story was good, they have spoilt it to make the 2 girls seem like heroes. The action is just too over the top. Natsumi's strength was fun when it was sort of realistic, but here they have gone too far (the foot braking thing has now become annoying).
The show was initially nice because it was slice of life kind of story with lots of love and fun. It does not work when its too serious.
Still see it if you like the characters and its also in HD.
