Looks the same as Suicide Squad
Going on the trailers, it looks to me like this will continue in the vein of Suicide Squad.
They won't have a good plot or story.
They won't have compelling characters, except Harley herself.
They won't care about source material - to respect it - or even really know about it - to move away from it in a new creative direction.
They will split the difference between the dark, macabre stuff and the funny, silly stuff without leaning enough into either to make it work.
And the only awesome thing about the movie, really, will be Robbie's performance as Harley Quinn.
