Take a look at the
IMDB page for July movies. Of the twelve movies there, there are only three which don't have any real plot information, Beyond and Jason Bourne which both say the plot is unknown, and the new King Arthur movie which just calls it an adaptation of Sir Lancelot's story, which might not be saying anything but is still more than "unknown." Hell, even the majority of other movies released after July have something more substantive than "unknown" written up for them.
Those descriptions are nothing more than glorified elevator pitches. They offer no specific plot details beyond vague set-up or introduction And, of course, the return of Damon as Bourne is also "plot unknown," and it comes out a week later. But is anyone worried about it? No.
My original point still stands.
Okay then. Write two sentence detailing what it's about beyond what I can infer from it being a Suicide Squad film.
It's a new commodity to most people. A significant chunk of movie-going public have never heard of it, so WB thought it wise to educate people. All three trailers are introduction to the group. Not one gives any substantive detail about the story.
On the other hand, people know what they're getting with ID4, Ghostbusters, Tarzan, King Arthur, and, of course, Star Trek.
Shit. DoJ comes out in nine days. Can anyone provide a substantive plot synopsis beyond "Batman and Superman fight because reasons?", which is implied by the title of the film. Even the idea that they team up in the end to defeat Teenage Mutant Ninja Doomsday is an assumption.
Honestly, this idea that, because Paramount is holding the cards chest is some indication they think it might fail is one of that most absurd theories I've seen presented on this forum yet. And that's saying something.
