The thing is, I love Kamen Rider (to the tune of currently over $5000), and I just can't seem to get into the heads of people who act like every season is supposed to be dark and all that jazz. Like, did we all take silly pills and forget that this is a franchise created for young children? Primarily to sell merch?
Like, yes, we can feel disappointed, as adults, when the storyline is a bit weak, or the pacing is off...but at day's end, we aren't the target audience. Like, we may get shows like Black Sun or Amazons, or movies like Shin Kamen Rider, but when it comes down to brass tacks, we're just adults, failing to grasp that the children's show will often be...well...kiddy.
The last two times we had a chance with the franchise (See: Masked Rider & Dragon Knight), we proved time and again that we didn't understand how Kamen Rider works. We just saw it as another Power Rangers-type show, and tried to run it all the same. Hence why both failed utterly at conveying the stories they were adapted from...much like every other Tokusatsu hero show we tried to adapt, poorly.
Nostalgia may keep the blinders on some, but let's be real - sometimes we judge these shows a bit too harshly, as people expecting top-grade from a Kid's-Brand toy show, often limited in scale due to budgetary constraints.
THAT BEING SAID, I won't tell a person they HAVE to like a season, even if their reasons for disliking it are milquetoast nitpickery, at best. One person's yuck is another person's yum. Hell, there's folks out there who actually really love Hibiki and Ghost...and Wizard is a guilty pleasure of mine, I'm just a sucker for good costume design and fight choreography.
The one season I just can't bring myself to finish thusfar is Saber. I don't know why, I can't put my finger on it, I just cannot bring myself to push past like...Ep.20-ish.
...Gavv's shaping up to be great, though, despite the theme being, y'know...snacks. I think Gaim taught all of us in the fanbase to not take a rider at visual-theme value. Things can go from lighthearted to hearbreaking in the snap of a finger, if the writing crew isn't pulling any punches.
