*Disclaimer*
Due to the nature of Mazinkaiser SKL, it only is appropriate that the following review contain gratuitous cursing. I apologize if you are offended by this.
What do you do with less than an hour and a half of runtime in a mecha series? World building? Character development? Technobabble? FUCKING. PLEASE. If you're making an entirely self-contained mecha movie, the most important part is the robots, isn't it? Seriously, just ask yourself: how many good mecha movies are there that aren't connected to an existing story? Mazinkaiser SKL knows exactly what it wants to do, and that's something that I give it props for. Can you handle it?
