You started it. Now it belongs to all of us.
As for reading reviews, Chibnall is absolutely correct. The best example of how reading reviews and online commentary totally screwed up a series is WestWorld Season 2, which twisted itself into knots trying to stay a step ahead of the online fans who guessed the original plan for the series, so the writers decided to make it even more convoluted and nonsensical just to preserve 'the mystery' rather than sticking to their original vision. Now, this doesn't mean that I'm a fan of the last episode (I'm not) but trying to react and adjust based on online feedback is a fools game.
