Ten years ago, the villainous scientist Dr. Hell led his wicked followers, known as the Underground Empire, in a struggle to destroy all of humanity. It was against these forces that the young hero Kouji Kabuto fought, piloting the legendary super robot "Mazinger Z." Kouji's victory stopped Dr. Hell's evil plan and returned peace to the Earth.
Now Kouji has left the pilot seat behind and become a scientist in his own right, following in his father's and grandfather's footsteps. Yet an unexpected encounter deep under Mt. Fuji triggers an even greater threat to mankind than ever before and alters Kouji's destiny forever. With humanity's fate in their hands, Kouji and Mazinger Z face a choice between good... and evil.
This reccomendation is based after watching the spanish (Latin American) version of Mazinger Z Infinity.
Toei Animation shows how can appeal and bring back old gems like Mazinger and Go Nagai's 50th Anniversary to the audience. While this movie is rated for all ages, I'd suggest if it's your first time watching any Toei's related to Mazinger or Go Nagai then be open to watch some soft ecchi scenes.
Story is rated as 6/10 for me because many of the stoyline is mixed between straight combat sequences and then a sudden drop of dialogue, explaining what's going on or why they did some actions. For fans
and newcomers you don't need to be explained who is who and why is Mazinger so important because it's all explained. Having some ecchi and funny scenes dros the tension and seriousness of the movie.
Art is rated 9/10, Toei A. Did a perfect job in the 2D and 3D departments, you'll enjoy a full 3D Mazinger Z and at the same time the 2D animation will appeal you because noone is a second hand drawn character, everyone looks cool and well detailed.
Sound is 8/10, I hope this is a mistake for watching the spanish (Latin America) version of the movie, because many of the OST tracks you can't hear them unless it's the Infinity version of the Mazinger Z Opening, so that was bad because the music it's real good.
Characters 6/10, You can see a mature Koji Kabuto, still your favorite dense main character because many of their friends and family already moved on with their lives and the good thing this movie gives him a true ending for this character, the same with others. For the new character that appears in this movie (LISA) it's the most important piece of this movie.
Enjoyment 8/10, it's not even 5 minutes in the movie and you're already enjoying the opening and the combat scenes, so it's awesome, Go Nagai's story is mixed and because of that you can expect some random stuff that will make you laugh any moment.
Overall it's a 7/10, if you're curious about Mazinger Z and mecha then give it a try, also this movie is part of the Go Nagai 50th anniversary so if you're interested in his works you can branch to Cutie Honey or Devilman after this. Hope this review can help you to interest in Mazinger and some old 70's (old-school) anime.
