I'll admit, Pokespe IS good. Memorable characters, almost nonstop action, and takes plenty of liberties with the source material.
The problem is that there are still flaws in and around those concepts. Though to keep short I'll just be deconstructing/nitpicking the above three points.
1: Deadpan, Polyanna, Runt, Simple, Neutral, Hero Archetype, Aloof, Ojou, Witty, Magnificently Domineering, Tsundere, Camp, Hyper, Wild, and Determinedly Protective. What I've done here is sort the main protagonists up to the BW arc randomly via a description of how best I could sum up their character traits. If you were to match them up with the proper protagonists, even if you got some wrong, you'd probably be at least 60% correct no matter what if you've read the manga all the way through. Unfortunately, the fact is that these personas usually end up whitewashed into "generic shonen hero" once arc climaxes start, and that even then, apart from comic relief characters like Dia's Munchlax and the 7 Pikaclones, there is no reflection of personality in the Pokemon that do all the real fighting for them. Of course, this is a flaw of Mon series to begin with, but let's move on.
2: Nonstop action might keep the story from seeming slow-paced, but when there's never any time for characters to relax and expand, the repetiveness of Monster of the Week
battles ends up boring and predictable.
3: Kusaka is an excellent madman. Creating subtle hints to future game content, and forging actual characters for protagonists other than stereotyped shonen heroes can be compelling. Yet he can tend to get a little ridiculous and annoying about this. Celebi/Shaymin ex Machina? An unexplained Hive Mind
Team Galactic? Turning N into Light Yagami? A Dracula reference with magical powers, hidden agendas, and possession of Darkrai? Small, strange deviations like that can turn off a fan of the source material faster than you'd think it does, people.
All in all, it's stuff like that that's made me lose hope in Pokespe. I'll still read it, but only because I'm committed to it, and because I have nothing better to do with my free time.
All criticisms and/or insults of my opinion (For example: "What did you expect from a story based on Pokemon?!") are welcome.
