I think your opinion is clouded by the opinion bubble you subscribe to.
People who want to moan about something expand far more social media energy than those who are satisfied with something. I don’t think a ride has opened at Towers where the social media comments are not excessively negative.
Look at you, you have expended far more energy in the Alton Manor topic than almost anyone else, it’s living rent free in your head, that’s what happens when people don’t like something, it niggles them. People who where happy just move on to the next thing.
I guarantee when Nemesis 2: The revenge opens tons of people on socials will moan about it. When Horizon opens tons of people will moan about that too. It’s just human nature.
