Ever since the Super Hero Taisen series became an annual thing, a lot of tokusatsu fans will probably tell you that a huge crossover film featuring both Kamen Rider and Super Sentai isn't necessarily a good thing. However one good thing that came out of 2015's Super Hero Taisen GP was Kamen Rider 4 - a web miniseries that expanded on events following the film as well as giving Kamen Rider 555 some much needed closure. With the release of Chou Super Hero Taisen in 2017 Toei are at it again with Kamen Sentai Gorider - another three-part internet miniseries featuring the aforementioned Rider/Sentai fusion team. More importantly it also features a number of returning Riders, including Kamen Riders Lazer, Blade, Baron, Marika , and Another Agito . This review contains spoilers for Kamen Rider Agito , Blade , Gaim and up to episode 23 of Ex-Aid .

Proving that you can't keep a good hero down for very long, after Kamen Rider Kuuga spearheaded the Heisei era revival of the Kamen Rider franchise it was immediately followed up with Kamen Rider Agito - a series that didn't just celebrate Rider's 30th anniversary, but the 50th anniversary of Toei as a whole. Kamen Rider Agito is particularly notable for not only being the first series to tackle a multi-Rider dynamic, but as an indirect sequel to Kuuga is also a rare example of continuity in the Heisei era. Finally  Agito was also Toshiki Inoue's debut as a head writer for the franchise. Inoue previously had several writing credits on Super Sentai (the most notable being Chojin Sentai Jetman ), with this series beginning the long (and perhaps turbulent) relationship he would go on to have with Kamen Rider.
