I'm dreading Christmas this year, wanna hear my festive shitspectations?
Really bad expectations in reaction to a movie or a game production revealing news about the upcoming project within an existing intellectual property, trying to create hype with claims it will be 'new', 'fresh', 'different', 'modern' or any other way deviating from the original (or previous) entries within the IP.
Title: "Alien: Romulus actor says film will be very different compared to Ridley Scott's original!"
Well, I got some shitspectations right there.
