Actually sticking with the franchise from start to present day seems like a pretty big achievement to me at this point, to be honest.
All the nonsense Pokemon has put me through over the years is horrifying. With the anime going in circles and having more filler than probably even Naruto - which had the grace to end after 720 episodes, whereas this is damn near 1000 now and won't stop for that - some games being outright terrible - 3rd, 5th, and 7th generation - the astronomical cost and quantity of the merchandise, Nintendo refusing to put old games on the eShop, just the designs of some of the Pokemon...this franchise throws so much crap at me; far more than I would take from practically any other franchise I've ever taken an interest in.
I've dropped games for far less than what Pokemon has done to piss me off - hell, I DID drop Pokemon Sun, because it finally pushed just a little too hard...and yet I still have plans to play Pokemon Moon somewhen when I've cooled down a bit and built up my patience, and if there's another game you can bet I'll buy it at launch and play it. As long as they keep making them, you can bet I'll keep buying them. It doesn't matter if I know I won't enjoy it, I'll still purchase and consume, purchase and consume, like a mindless automaton. Literally nothing changes with this franchise, and nothing has changed in my approach to it.
It'd be no small exaggeration to say I have come to really dislike Pokemon, as a franchise. And I still keep buying the games. And occasionally watching the anime. And generally taking an active interest in it even though I have absolutely no reason to and no idea why I still do. It irritates me far more than it does please me now, but I STILL keep coming back. I can't let it go. It's got its claws well and truly in, and the weirdest thing is that, despite my excessive whining and complaining, I don't care. I KNOW it's terrible, but some twisted, masochistic part of me still gets some form of enjoyment out of this mess.
That it can keep my attention like this, and that I've stuck with it this long, is definitely an achievement. Although I'm not sure if that's a good or bad thing, and I'm not sure who it's an achievement for - me or the franchise. Either way...
