i wasn't saying to avoid it. the idea is "at first a new fan feels ashamed because they're not supposed to like the show, but eventually they think it's awesome."
no, Kamen Rider is not Sentai. Super Sentai is a separate series created originally by the same person as Kamen Rider. Sentai means group, and Kamen Rider ends to focus on one or two riders. the genre is called Tokusatsu.
