Eh, the Urobutcher has been downright merciful with Gaim so far, I mean, nobody we've really cared about has died so far. Hase wasn't around long enough to grow TOO attached when he bit it, although it was played VERY well when he did.
I'll be generous and say two good years. OOO is certainly better than Decade (though that doesn't say much) but still had the "copy Den-O syndrome" horribly mashed in.
How did Wizard do anything to change up the W (really the Den-O) formula? Other than having much less plot and much more "LAUGH AT US WE'RE SO FUNNY!" junk?
Looks like someone gave Agito the G-3 treatment(For the folks without the memo, I mean a synthetic bodysuit based on a magic/biological rider.) and... It's COUNT ZERO, good Lord, how do people screw that one up. I didn't even need subs to tell what they were saying, come on. I understand how you can get councilor, but you really should know better. This is Kamen Rider, there are no councilors. *Cue Drive's day job is therapy or something.*
Anyway, as for copying Gaim's formula... WHAT formula? Seriously, I don't see it other than super powered individuals come into conflict with monsters and each other, which is pretty much every superhero ever.
