Celebrating Kamen Rider's 999th To 1,000th Episode
The 999th episode had Kougami plan in making a "reboot" of Kamen Rider OOO. It has a throwback to Kamen Rider 1 (which I am yet to see). It has Eiji cast as Takeshi Hongo. I do find this funny considering that Kamen Rider 1 is that old school. In terms of Showa Riders the only ones I've seen from start to end are Kamen Rider Amazon, Kamen Rider Black and Kamen Rider Black RX. I've seen most Heisei era Kamen Riders so I can't comment too much on the Showa era.
I'll admit that the actual battle in the show isn't all that well done. I couldn't really expect much from Yonemura himself. But it was a nice tribute to celebrate Kamen Rider's 1,000th episode even if it isn't much. Fortunately, it's not a real disaster compared to what happened with the first Super Hero Taisen movie.
