Eh. Of the series I've seen, I'd rank Dopants at the bottom of the list too, right behind Mirror Monsters.

Also, just finished episode 7 of Blade. Still have no idea what the overarching plot is, but it's getting more exciting, at least.

I think there are a lot worse designs than the Dopants. I like the Greed well enough, but I thought most of the Yummy designs were really weak; the Orphenochs are incredibly bland; Worms never did anything for me; I find the Imagin tend to be way more miss than hit. The Dopants, on the other hand, I generally find really good - not the best monster designs ever, but I like them a lot.

True, the Yummies were all very weak, I've found the Worms to be good enough, better than the Dopants anyway.

I've always thought the Worms were pretty low on the totem pole, mainly because they're all fairly generic, but I'd still rank them over Dopants. Yummies aren't incredibly innovative either but still pretty good looking.

The only villains I've ever really enjoyed are the Zodiarts and Fangires. Of course, X's enemies also had the greatest of comedic values too, but beyond that, I'm interested in heroic designs more than anything.

X had some great monster designs. I liked the ones from the earlier part of the show more, though; the mythological villains, not the criminal ones like Ant Capone or Starfish Hitler.

Oh yes, speaking of monsters, I kind of like the Undead designs. Granted, I'm only 7 episodes in, so this gives ample time for them to disappoint me, but at the moment, the monsters I've seen I really liked how they looked.

It's a shame the quality of the video is pretty much reaching theater camcoder levels...

The Undead are great designs, yeah. Not quite up there with the Unknown, but close.

Well I decided to give Hibiki another try after I stopped around episdoe 15 when it first aired. I made it through the first 10 episodes and so far, it isn't nearly as bad as I once though, but Asumu is still getting on my nerves. Every freaking episode something stupid happens that makes him a depressed baby. This dude is like the original emo, only without dressing the part. Anyway, Hibiki himself is kinda cool, and I love Taiko drums, so hearing them played in this show is pretty awesome, Ibuki is all right, he has a trumpet though, and I am not a trumpet person, so he really isn't my thing. I forgot he was played by the actor who played Mamoru in Sailor Moon though, which is cool. On the other hand, the Makamou are the worst Kamen Rider monster designs ever. Not to mention they have some of the worst effects. The battle against the crab has got to be the worst CGI ever from any of these shows. The problem is, outside of the giant monkey and turtle, they look so freaking fake that it pulls you out of the show a bit. And the male/female combo is the same thing every episode, with really bad costume designs.

Overal thus far, like I said, not as bad as I once thought, so it is not the worst KR I have ever seen anymore, but it has a lot to fix if it wants to be better than "meh."

To the other discussion about designs, I'd say my top five pics are:

Gorgom (Black)
Undead (Blade)
Fangire (Kiva)
Unknown (Agito)
Dopant (W)

Although, the Orphenochs were really unique too...

Monster, ranking wise, would be:
Zodiarts
Fangire
Undead
Imagin
Worms

Anyway, I've finished episode 9 of Blade. It's starting to pick up. Tachibana's little story arc is progressing nicely (And he was just captured by who I'm assuming is the Peacock Undead, so I'm curious as to what happens next), and I'm liking Kenzaki.
That said, they're really getting their mileage out of the "Shattering Tachibana" clip. I think I've seen it 6 times now...
