So this 2011 Anime is some kind of tribute movie to the old Mazinger Anime series from 1974... which is a cool thing but I think most people who watched the old Mazinger won't ever hear about this movie cause they are way too old... But another thing that results from it being the movie to a series is that the creators assumed that you will more or less know what's going on and who the characters are. So I have never watched the old series and the missing character introduction and introduction to this world where apparently giant mechs are quite usual is a problematic thing cause you can't really dive into this movie that way. The animation is good, the English dubbing is also good and I certainly can't complain about the music but after over 20 minutes of watching I was as clueless as in the first minute and the overwhelming amount of characters whom I don't know makes it even harder to follow. I can not recommend this movie to anyone who doesn't know the series, but the people who know it should probably give this movie a try.
