A nice finale to the series (although there's two more episodes after this). I won't say it is spectacular, but we got a cool fight between Infinity and the souped-up Gremlin, and an emotional finish. I thought they'd bring back Koyomi a la Phillip/Ankh/Kengo, and was surprised that they let her stay dead (albeit returned as a ring). Kudos to the producer for letting her death be meaningful instead of retracting it with some kind of Deus Ex storyline.
Since I watched the episode in raw, I do wonder why Haruto reverted back to Flame Dragon after his Infinity was broken. And how did he block Gremlin's spear attack with just his bare hand, and attacked him while Gremlin was stunned? Did he get super-charged from the memories of Koyomi or something? But anyway, that last Rider Kick (fueled by Koyomi's ring) was quite awesome, and Gremlin/Sora did go out in a spectacular fashion. The epilogue was long, though, but I'm glad to see what everybody get to do after the Phantoms were finally defeated.
It's not cool for us to have to wait 3 weeks before Gaim starts, though.
