You're logic is flawed in so many ways. I was not suggesting that KR was going to end, not sure where you got that idea. The sinking ship analogy applies to each series though.
That's what I said, I said "series", not "franchise" is not going to end. Read again since
IT'S YOUR LOGIC THAT IS FLAWED IN SO MANY WAYS, or you just have trouble reading. Again, the "sinking ship" analogy still doesn't apply to
ANY SERIES, because again, Toei isn't going to abruptly end it without an ending. It's going to finish whether it was rushed or not, so the ship
IS going to reach its destination.
I watch KR on a semi-regular basis. Kabuto was one series I did not finish, because I personally hated it. I saved literally hours worth of time from NOT finishing it and was in turn able to read ep. descriptions/breakdowns and other tidbits of info on the remainder of the series from the internet, in what probably took less than an hours time total. Basically, I know every major piece of info that those who watched it did without all that wasted time. The only advantage you have over myself is a visual of what happened. That being said, I don't feel left out. You act as if all KR series are connected. So not true. Heck, the majority of Hesei era KR series aren't. It's just like PR and Sentai (with the exclusion of the Vs. movies and PR's occasional team-ups), it's generally not an ongoing tv show in terms of continuity...it's called "series" for a reason. Each series, for the most part, stand on it's own.
Haven't you seen what Decade, Double, and OOO's have been doing lately? You seem to be watching a different show if you can't see that all the series are being connected. Even if the basis is not the story, it is still a Kamen Rider show, which again, I'll watch mainly because I always want to see what Toei has come up with. You may not have the reason and time to finish what they give you, but some people have a good reason to, mainly again, to have an objective view on everything.
And it's called a "franchise" for a reason. Some people are a fan of the franchise, hence wanting to see everything, even if the story doesn't suit their taste. You might only love a specific Kamen Rider series or whatnot, but some people love the franchise as a whole.
I'm not saying that it's a bad thing to be a completionist, but logically it just doesn't make sense to be one myself.
Then respect the simple fact that some people like to complete things. Not everyone is the same as you, so learn to respect other people's opinion.
Some people just want to finish a whole series in order to have a final objective critique on it, if you're not that type of person, I respect that... But learn to respect people with different views from yours.
