Is Fourze a good entry Kamen Rider series?
I think that it is. It's unlike other Rider shows in that it's very lighthearted, but that's one of it's best parts I think. I loved all the characters, the season-wide story arc was well thought-out and easy to understand (compared to the nonsense in some past Rider shows), it had awesome music, and the suits and powers took heavy advantage of the NASA space theme (it was a lot more literal and on-the-nose than Megaranger's suits and powers were).
Of course, don't expect something as serialized as Gaim; the core of Fourze is still the bi-weekly high school hijinks of a bunch of kids that form a club (much like Megaranger). However, the characters change and we learn more about them as the show goes on, and by the ending it felt like the characters went through a lot; as opposed to Megaranger which the characters stayed pretty much the same all year.
The villains are also a lot better than Megaranger. Sure, Mega had the Nezirangers, but if you saw In Space, then you know exactly what you're getting in Mega. All In Space did was copy that arc with a 1:1 translation. The rest of the show's villains are awful and go out in really anti-climactic ways. However, with Fourze, I felt the villains were more relevant characters to the plot, and were significantly more sympathetic to me. The final boss of Fourze ended up being a relatable character and kinda made you feel sad how things came out for him; but for the final boss of Megaranger, it felt like something the writers gave up on very early in the show.
