You mean all of it? As far as I know, Try was an entirely anime-original story. Unless you mean the filler within the filler season which, yeah, made me want to pop my eyes out with my own thumbs. Granted I don’t know the books so I could be mistaken about Try being all filler, but that’s how I’ve always heard it.
Try ATTEMPTED to do neat things, and for awhile it seemed like it might turn out better than it did. They killed off whining brooding emo villain Valgaav half-way through, it seemed, but then they brought in two more villains who were even LESS interesting. And they looked lame. I still don’t get how they could make Almayce look so dang cool, but then make Whozits and Sirius look so freaking bland. But that’s besides the point.
For awhile it appeared the story might actually elaborate on the grey area regarding who really is good and evil, and how Gods and Monsters aren’t as two-dimensional as they appear… and then right at the very end they throw all that away, bring back the brooding ponce and have one giant team-up against the big ultimate baddie. Yawn.
At least Xellos had some really awesome moments in Try, that’s about it.
