I dont know why people hate that theory so much.Its just a dumb little theory about sun and moon.I dont think its happening but if it came true and it was a soft reboot i wouldnt hate it.I like the idea of them trying something new.Plus all the connections with alchemy is cool,learned a few things i didnt know. Not as bad as the recent matpat stuff
It's ruffling to me because what he's arguing is a hard reboot and most of the Pokemon I like are from later generations.
If you read the post you quoted for example you can see it's a hard reboot he's describing rather than a soft reboot.
If it was a soft reboot I might be mildly skeptical but I wouldn't be bristling up like a rabid animal. Heck, TV Tropes classifies Gen 3 and Gen 6 as reboots, and the alternate universe theory essentially implies a soft reboot with each and every game. That's fine.
What the theory guy wants is a complete scrubbing of the entire series, with the point of that post being that his desire is specifically his vision of such. That's what's got me worked up.
That and while it may just be the YouTube comments I read jinxing it, his presentation has a dramatic flair that serves to exaggerate the perception one has of whatever he's saying. For someone with a positive view it might come off entertaining, but if one feels a bit uncomfortable with the idea of all of their favorite Pokemon being purged. . .
