>>4248927302 was just shit, it had nothing to do with ADVENTUREEEEEEEEEEEE.
About Konaka, it's more that he has insane ideas that work but he hates having to explain to the suits that kids can take watching a genocidal alien monster sifting through a girl's memories of her mother's death in their toys commercial. Remember that this is the guy that made Lain when left on his own and did the D-Reaper arc when lorded over by a toy company.
Of course a studio that only cares about Pretty Cure and a company that only has eyes for Gundam and Kamen Rider are going to go for a sequel to ADVENTUREEEEEEEEEE over Renamon getting dissolved and Takato traveling back in time; all the consoomers that watched Angela Anaconda have nostalgia for it.
Frontier, though. I liked it but it was kind of shit. The villains won nearly every fight, to the point you stopped believing the kids could win without some writers shenanigans.
