RT usually, is very reliable; with several well trusted outlets reporting to them when review embargos are lifted (IE, The Hollywood Reporter, Variety, Entertainment Weekly, E.T.C.).
There is another reason why I trust them, because of that the film lifted it's embargo day's before the release of the film. It doesn't work out, much like what happened with Fantastic Four, and other IP's.
Plus, it does look like that most of the film has been given away from all the trailers; but that's me. I hope people are wrong, as you have great talent, from Margrot Robbie, Jared Leto, Will Smith, Viola Davis, and Scott Eastwood; but for now, I am not hooked into it.
It's also due to because I don't like the way they are approaching it, backwards and not in the best way that they can do it.
