Why?
If you don't like it why would you deprive other people who actually enjoy it?
People sticking the knife in at a mediocre sequel has destroyed many franchises.
Ghostbusters had only just come back and all the hate has pretty much destroyed any chance of a future movie.
Internet outrage didn't kill Ghostbusters' franchise potential, making $229 million on a $144 million budget did.
Studios don't give a fuck about what people think of their movies online. If it makes money, the sequels will pour in.
Fallen Kingdom isn't going to make less than a billion worldwide. So stop freaking out. No one's depriving anyone of anything. If your enjoyment of a movie or otherwise is that impacted by what anonymous nobodies say, start evaluating yourself.
