I've just seen it, and thought it was quite enjoyable. Still, I thought I read somewhere that this one was supposed to have some relevance to the plot of the rest of the series, and I'm left wondering what it will be.
Also the bit of Kokuto's betrayal was a bit cliche, I wish that they had handled that differently.
I loved his Hell Armour though, and I hope that it returns in the show.
