These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternate Character Interpretation: A possible case mid-way through the show. Was Torque's attempt to turn Thrust against Xaviax a grab for power, or did he feel genuine remorse about what he'd done so far and wanted to make amends?
Broken Base: Kamen Rider fans are quite divided. Some think it's a great adaptation and there are even those who claim it's better than Kamen Rider Ryuki due to the storyline and American made footage being pretty good. There are those who hate it for various reasons, some of whom hate it just for existing.
Crowning Moment of Awesome: When the Cho brothers confront Len for the first time, arrogantly assuming they have a two-to-one advantage, Len gives them a lesson in humility by snatching their decks right out of their hands and kicking their asses all over Ventara, all without transforming.
Kit and Adam announcing their entrance with a double Strike Vent against Xaviax.note It doesn't hurt to realize that this is something fans of Ryuki had been begging for since Ryuga (Onyx's Japanese counterpart) first showed up in the Ryuki movie.
Epileptic Trees: It's never directly stated what JTC stands for. Wrath's unique gold belt, sheer power, and a few mentions between Len and Vic seem to imply that Nolan, the original Wrath, might have been the leader of the Ventaran Kamen Riders.
Game Breaker: Wrath. And how! Especially in the actual Wii video game based on the series.
Germans Love David Hasselhoff: Although the show bombed in the US (the market it was made for) and was cancelled before finishing its run, Dragon Knight is insanely popular overseas, especially in Japan, with a DVD release and three music albums. DVDs also came out in Germany and Latin America. As a matter of point, Dragon Knight is so popular in Japan that they've started releasing action figures of the Riders - and these are specifically labeled as the Dragon Knight versions, not the Ryuki originals.
The Japanese are also lucky enough to get a sequel in the form of a novel.
Growing the Beard: The first five or so episodes are awfully slow, with the plot poorly explained and not even that many Monsters of the Week to fight. The pace picks up once Torque and other Riders start showing up and getting in each others' way.
Ham and Cheese: William O'Leary, the actor who plays Xaviax. Also Mark Dacascos while playing Xaviax in disguise.
And it works really well in one of his last plans. Not only did he capture Earth's version of Len's old mentor, Kamen Rider Wrath, and turn him into little more than a puppet for his own whims, but Xaviax posessed Wrath and used him in open combat against poor Len. And when it looked like Xaviax was finally vented, he stood laughing as Wrath's body was dissolved into the Advent Void, grinning at Len. And then he took Kit's deck, just to rub in how pointless his sacrifice was.
Iron Woobie: Thrust may be short-tempered and arrogant, but he's had his entire life ruined by Xaviax's machinations and just wants it back.
Mis-blamed: It's frequently believed that DK was cancelled by CW 4Kids; in truth, the last two episodes just didn't air before the cut-off point where old shows were cycled out for new ones.
Moral Event Horizon: When Kit finally realizes Torque's been playing him like a fiddle the whole time, Drew smugly admits it and then vents Camo, a potential ally to his cause, in cold blood.
Narm: Kit trying to make a sandwich and he struggles about not having what it takes to be a rider and his choices and almost destroy the sandwich.
Replacement Scrappy: Although not outright loathed, many viewers still preferred Sting over Kase.
Tear Jerker: A huge one in episode 19. Chris gets vented protecting Len from Strike's Final Vent. The only thing that makes it sadder? Len and Kit saluting, fist over heart, as Chris did when as he disappeared from existence. Semper Fi, Chris. *sniff*
They Wasted a Perfectly Good Character: Camo is barely in two episodes before he gets vented. We never see his Final Vent, his Advent Beast, or- probably his most interesting ability- Copy Vent. note Camo's Ryuki counterpart- Kamen Rider Verde- has the ability to take on the appearance and powers of any Rider he's fighting. If the Dragon Knight Wii game is to be believed, Camo has this power too, but never gets the chance to use it.
Genocider- the result of Strike's Advent Beast fusing with those of Sting and Thrust- is only briefly seen in one episode and never really put to any use.
To a lesser extent, Spear- who gets vented after barely being in four episodes and whose Advent Beast and Final Vent we also never see.
Incisor was only in three episodes before being vented, but his status as The Scrappy meant most weren't too broken up about that.
