I’ll predict The Rise of Skywalker to do $700,000,000 domestic and $1,400,000,000 worldwide. That’s more than The Last Jedi and less than The Force Awakens, very respectable.
This is of course before seeing a full trailer and experiencing the full marketing hype. Some positive word of mouth combined with the holiday season could considerably increase those numbers.
Not everyone who didn’t like The Last Jedi is a hater or a troll. Likewise, not everyone who enjoyed it is a undiscerning fanboy who just eats up whatever they put out. Broad generalizations about large groups of people are bound to have multiple flaws, so why not just ignore them.
