The Blade movie had Kiba and Murakami (Horse and Rose) as the two arguing guys at the job interview Mutsuki goes to, and Kaido (Snake) is the mall security guard. I think the first Den-O movie had Tadokoro from Kabuto and Todoroki from Hibiki as ninja dudes, but that was it. They're not as in-your-face about it as the Ryuki one though, where it might as well have a caption that appears at the bottom saying "Look! A cameo!"
I really like the Ryuki movie ending, for the most part. It's not a movie I can just sit down any watch any time like some of the more recent stuff, but I always enjoy it in context. The problem is, like Missing Ace, it needed to be made when it's supposed to take place (at the end of the series.) It was even originally promoted as being the real ending you had to go see in theaters, which is a weird move, but kinda gutsy. Also, it's the last time I remember any real secrets being kept where the movies are concerned- I don't think they published any photos of who Ryuga really was until after the series wrapped and the movie was out on home video (I know it's obvious in retrospect, but I think it was cool that they did that.)
The TV ending's all right. I don't mind the reset because my way of looking at it is, everything still had to happen for it to not happen. The problem is though is that I think it's more the Kanzaki siblings' doing than Knight's, who "wins" and saves Eri, but then looks like he dies or passes out, and the whole world gets rebooted anyway. Unless that was Ren's real wish, to un-do the Rider battle (I'll admit, I gotta go watch it again.)
I like how the movie basically says "screw the rules", kills off/melts down the Kanzaki siblings, and does crazy nonsensical stuff like having them fight in the real world or transform without mirrors (it took me a few viewings before I got that, but notice how the dragons just appear out of wherever rather than coming through the mirrors, which by that point are all smashed.) It breaks every rule in the book, but if one show should have all its rules broken, it's Ryuki. Some have seen the final cliffhanger as a suicide run, but I always thought it was another version of the battle from the penultimate episode of the TV series. There, Shinji was going in gravely wounded, and they still manage to win. Here, they're going in guns blazing so they're pretty much destined to win. I just wish we'd gotten to see what comes next. I imagine it'd be pretty awkward.
