There was never any "simpler writing" on Westworld to go back to.
Of course there was. The overall story of S1 is obvious by the end of the first episode, and can be easily summed up in a single sentence: "The hosts are gaining consciousness, and when they do, 'these violent delights [will] have violent ends.'" There were reveals along the way (the split timeline/old William, Arnold and Bernard's history, the extent of Ford's planning), obviously, but they all supported that general direction, and that's where the season ended up.
In S2, however, Dolores was out to exterminate all humans, except for when she bafflingly spared old William, and Maeve was looking for her daughter, and Bernard was dealing with self-inflicted (?) amnesia and generally just wandering around. And then at the end of S2, Dolores still seemed pretty bent on mass murder, but also brought Bernard into the real world, because... it was the sporting thing to do? There wasn't a clear direction beyond the prospect of hosts getting off the island. And then the post-season tag was laughably nonsensical. (Even if its old William is a bot not previously shown on the series, why would anyone be wanting to replicate human old William's character for "fidelity"?)
Then in S3, Dolores has overcome most of her murderousness between seasons, and is now fighting to dismantle the Evil LinkedIn society because Control is Bad, but she's also guiding Caleb along her grand plan by feeding him information in bits and pieces, and Maeve is now fighting Dolores, because if she does, someone will make her a version of her daughter again, maybe? And William is institutionalized, and Bernard and Stubbs are wandering around, and Dolores-Hale is still pretty murder-y, but also wants to be a Real Mom... it's a bit of a mess. And instead of contending with his part in all the goings-on, old William is just up and killed in a bunker, and now there's a William murder-bot. Yay?
If you don't see the drift away from simpler writing in terms of narrative progression in the above...
