People on the Internet have a remarkable amount of power. When the first trailer appeared for Sonic The Hedgehog, the animation of Sonic didn't look quite right. It was kind of creepy. So people complained en masse. The production studio was so affected by this that they spent an extra $10 million over their $90 million budget to fix the animation, and the result was a kid's movie that surprised the critics by actually being good. It wasn't great, but it was passable entertainment.
The 2016 Zack Snyder movie Batman vs. Superman Dawn of Justice was fairly good, but the follow-up 2017 film, Justice League, was a disaster. Zack Snyder had to leave the project before it was finished due to the death of his daughter. The movie was finished by Joss Whedon, who has done great work on television and in the Marvel films, but his cut of the movie didn't quite work. As a result, there was an Internet campaign to, "Release the Snyder Cut", even though such a thing probably didn't exist. People were saying that it would never happen. However, the campaign never stopped, which lead to $70 million being spent so that Zack Snyder could release his version of the film on the 18nth of this month on HBO Max, an online streaming service. The early reviews are in, and the critics for the most part like the new version.
Gina Carano is a former wrestler who did a fairly good job of playing the character Cara Dune on the Star Wars streaming series, The Mandalorian. (I can't recommend this series enough.) However, she got into it with some fans on Twitter about her posts not being politically correct, which led to a several-month-long campaign to get her fired. I think that Gina Carano did nothing wrong, but Disney eventually gave in and fired her. Now, the same outrage mob is trying to go after Bill Bur and Rosario Dawson, both of which have also played on The Mandalorian. Meanwhile, Josh Whedon has fallen out of favor with the public for alleged bad behavior.
