I'm not sure if this was true and Reddit isn't really a reliable source for stuff but I read online there and a few other places that season two the writers were a bit ticked off with online forums for predicting everything so they kept changing things in the show during season 2 to out spoiler the spoiler freaks who kept guessing stuff.
So the writers were agitated by online people. That is not the way to make a good show.
I've also heard this. It's apparently why there was a longer wait than expected between season one and two.
From NME:
"According to Deadline, Nolan also revealed that Reddit users had “already figured out” a major twist for the show’s second season, forcing the writers to change what they had planned.
“Reddit has already figured out the third episode twist,” he said. “So, we’re changing that right now.
“It’s annoying sometimes when people guess the twists and then blog about it, but the engagement is gratifying, on one level, because if someone guesses your twist, it means you’ve done an adequate job [of structuring the series].”
While Nolan was the first to applaud the fans’ pretty spot-on theories, he did ask people to stop guessing twists so Westworld can get back on screens as soon as possible.
“You can’t complain when people are that engaged,” he added. “It’s very gratifying — but stop doing it, please.”
Honesly, I think the show might just have run out of steam after season one regardless. I'd have preferred a miniseries with a few questions left unanswered.
