That said, I can't recommend this as a stand alone since when I watched this I thought this was the conclusion to the OVA series and not a separate series which is why I had a high enjoyment of this so much because of the way it seems to be saving the Mazinkaiser OVA series in general.
The premise, action and events were so good (for a Super Robot lover) that despite the poor boss battle scene at the end, I rate the story a 10 but that last battle scene is still something that needs to be watched out.
I can't speak for all Super Robot fans but I think most of us have been desensitized by the crappiness of an end battle because we're so used to seeing classic Super Robots killing off their opponents eventually so if you're not used to do this the story could even sink down to a one just because of the ending.
Everything else though is so gripping and suspenseful which is rare for a Super Robot series and despite the predictability it can be forgivable because of the destruction and premise that surrounds this series compared to the OVA before this. This is simply one of those series that you need to have bundled with that longer OVA series or else the whole Mazinkaiser series doesn't feel as epic as it is.
Still, this is a 7 mainly because there are better "epic" Super Robot plots out there but seeing as I haven't even read most of them, it's hard to really gauge how subpar or exciting this is but general fans of Super Robot shows won't be hurting themselves from watching this show to the end as long as they don't get too hyped up around the prospect of Mazinkaiser having an OVA (which if you watched the OVA series before this will already tone down any excitement you may originally have for Mazinkaiser)
