This series is hailed as a classic and masterpiece of the mecha genre, but why? it's a knockoff of transformers with a cool main mecha and good animation overall, but that's it. The longer the runtime, the more it gets boring and all the mysteries sorrounding the cast of characters suggested in the intros of the first episodes are thrown away for a uninteresting sequence of fights between zonders and mechas mixed with toy product placements. The problem is, since this is supposed to be based on 70's mecha animes, I don't remember the plot being so exhaustively meandering in mecha shows like Voltes V or Daimos, in particular in this one the plot and characters were really interesting albeit not exactly original material (Romeo and Juliet mixed with War and Peace). Hell, even Golion King of Beasts (!) had more plot than this show. Here you have no connection with the characters, no plot threads, nothing. Just a catchy intro song, some nods to other animes, flashy and colorful animation, a good main design of the titular mecha and...nothing else at all. Disappointment is an understatement. NOT recommended.
