I watched the Nihon DLC the other day, and jotted down my thoughts since I was without internet at the time.
I did skip most of the Fourze section and most of the final battle, however.
The entire process of Fourze entering the Underworld. I was like "What in the actual **** is this?" Though it was answered later, at least.
Anything having to do with Fourze Meteor Nadeshiko Fusion States left me literally unable to form words.
The whole "Where are we?" "You don't need to remember" and how funny they adults are acting would make me go "Hm, did they molest me?"
As soon as the owner takes the helmet off, the general look of it is "Kill it with fire!"
And...eh, that's about it. Not as bad as Core, but not as good as Megamax or the first one.
