Well TC, our opinions are both aligned and opposed. I too despise Blade's characters, their pitiful excuses for "arcs", the general meandering lack of focus that plagues the first 25 episodes or so, and the incredible lack of reason the characters base their decisions on. The first 10 episodes where they were establishing the world especially.
What reason did those characters have to think any of the things they thought? Why was Garren supposed to have destroyed the facilities? Why was the comic relief character so racist against Hajime? Why did the chick think that her father was the one that let out the Undead? Sure she was right, but that's not because she gave it an ounce of rational thought!
And add to that the fact that I HATE the fight choreography and use of special effects. It's all flash and no substance. None of the hits feel "real", it's just a lot of sparks and not a lot of impact. And I hate the card system EVEN MORE. It's hard to pinpoint what I don't like about it, but the best I can figure it's to do with how atrociously it interrupts the pacing of fights. They have to pull out the cards, show them to us, slide them one by one, do a pose...ugh. Other shows do that too, but they do it with better flow. Decade actually did cards RIGHT (the only thing it did right).
But what's more, they have all of these card combinations...and they use the same ones over and over! Even in situations where there is NO REASON to use that particular combo! WHY would you use the Genesis/Fire/Kick combo as a head-on attack when the entire point of the Genesis card was to be deceptive? It's not like both images perform the attack, one of them disappears! It was lazy and stupid and I hate it.
BUT, having said all that...like a light-switch, one the show hits Jack form I absolutely love it. Love, love, love it. The action gets better, the characters get more intrigue and development that make sense and flow from one event to the next...it's just all around better, great even. And the ending is my absolute favourite in the franchise. It's the single best solution, it's the one I thought of when trying to figure out how they can get out of a roach apocalype. It was brilliant.
So my feelings are mixed.
