It would be an understatement to say that Justice League’s production suffered from bad press that actually began before filming started. Batman v Superman: Dawn of Justice was even more divisive than Man of Steel, and numerous fans pointed out that Zack Snyder wasn't a good storyteller, although his movies’ visuals are almost always top notch.
Then came the announcement that Snyder was stepping down as director, that Joss Whedon would finish the movie, that extensive reshoots were necessary, and so on and so forth.
These might be seen as bad omens, although such things sometimes prove baseless (remember Wonder Woman).
And here’s another bad sign: According to Comic Book, the Justice League premiere will take place three days before the movie's release, and Warner Bros. has decided to continue the review embargo until the premiere date. Given the track records of most of the previous DC Extended Universe flicks, it’s easy to predict what the majority of comic book movie fans might be thinking.
Furthermore, that there won't be a press junket for Justice League, which is also pretty weird for a movie of such magnitude:
There will be no U.S. junket for #JusticeLeague, per WB

Since this is the team’s first big-screen outing, it’s not surprising that fans are a bit concerned about recent developments. But again, the rumors that plagued Wonder Woman turned out to be baseless, and the studio lifted the review embargo for that film five days before its release.
Justice League will hit theaters on November 17.
